Multicast Routing and Forwarding Commands on Cisco ASR 9000 Series Router
This module describes the commands used to configure and monitor multicast routing on Cisco ASR 9000 Series Aggregation Services Routers.
For detailed information about multicast routing concepts, configuration tasks, and examples, refer to the Implementing Multicast Routing on Cisco IOS XR Software configuration module in the Cisco ASR 9000 Series Aggregation Services Router Multicast Configuration Guide.
accounting per-prefix
To enable accounting for multicast routing, use the accounting per-prefix command in the appropriate configuration mode. To return to the default behavior, use the no form of this command.
accounting per-prefix
no accounting per-prefix
Syntax Description
This command has no arguments or keywords.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
The accounting per-prefix command is used to enable per-prefix counters only in hardware. Cisco IOS XR software counters are always present. When enabled, every existing and new (S, G) route is assigned forward, punt, and drop counters on the ingress route and forward and punt counters on the egress route. The (*, G) routes are assigned a single counter.
There are a limited number of counters on all nodes. When a command is enabled, counters are assigned to routes only if they are available.
To display packet statistics, use the show mfib route and the show mfib hardware route statistics commands. These commands display "N/A" for counters when no hardware statistics are available or whenthe accounting per-prefix command is disabled.

address-family (multicast)
To display available IP prefixes to enable multicast routing and forwarding on all router interfaces, use the address-family command in multicast-routing configuration mode or multicast VRF configuration submode. To disable use of an IP address prefix for routing, use the no form of this command.
address-family [vrf vrf-name] {ipv4}
no address-family [vrf vrf-name] {ipv4}

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
Use the address-family command either from multicast routing configuration mode or from multicast VRF configuration submode to enter multicast IPv4 address family configuration submode.In Cisco IOS XRSoftwareRelease 3.7.2 and later, basic multicast services start automatically when the multicast PIE is installed, without any explicit configuration required. The following multicast services are started automatically:
•
Multicast Routing Information Base (MRIB)
•
Multicast Forwarding Engine (MFWD)
•
Protocol Independent Multicast Sparse mode (PIM-SM)
•
Internet Group Management Protocol (IGMP)
•
Multicast Listener Discovery Protocol (MLD)
Other multicast services require explicit configuration before they start. For example, to start the Multicast Source Discovery Protocol (MSDP) process, you must enter the router msdp command and explicitly configure it.
To enable multicast routing and protocols on interfaces, you must explicitly enable the interfaces using the interface command in multicast routing configuration mode. This action can be performed on individual interfaces or by configuring a wildcard interface using the alias command.
To enable multicast routing on all interfaces, use the interface all enable command in multicast routing configuration mode. For any interface to be fully enabled for multicast routing, it must be enabled specifically (or configured through the interface all enable command for all interfaces) in multicast routing configuration mode, and it must not be disabled in the PIM and IGMP configuration modes.
Note
The enable and disable keywords available under the IGMP and PIM interface configuration modes have no effect unless the interface is enabled in multicast routing configuration mode—either by default or by explicit interface configuration.
To allow multicast forwarding functionality, while turning multicast routing functionality off, interface-inheritance disable command on a per interface or interface all enable basis in PIM or IGMP configuration mode.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
The Multicast Forwarding (MFWD) process exists on each line card and assigns hardware counters to each (S, G) route. Additionally, one global counter is assigned for all (*, G) routes, depending on resource availability.
To clear the set of counters for (*, G) routes, the MFWD process assigns a single set of counters to count packets that match (*, G) routes. Consequently, the clear mfib hardware route statistics command must be used in a form that either clears counters on all routes or matches all (*, G) routes.
Note
This command only clears MFIB hardware statistics counters. To clear MFIB route packet software counters, use the clear mfib counter command.

Use of the interface-inheritance disable command together with the interface type interface-path-id or interface all enable command under multicast routing address-family IPv4 submode separates PIM and IGMP routing functionality from multicast forwarding on specified interfaces. You can nonetheless enable multicast routing functionality explicitly under PIM or IGMP routing configuration mode for individual interfaces.
Note
Although you can explicitly configure multicast routing functionality on individual interfaces, you cannot explicitly disable the functionality. You can only disable the functionality on all interfaces.
Used from the address-family ipv4 configuration submode, it prevents IGMP and PIM from inheriting the multicast-routing interface configuration.

Examples
The following configuration disables PIM and IGMP routing functionality on all the interfaces using the interface-inheritance disable command, but multicast forwarding is still enabled on all the interfaces in the example, based on use of the keywords interface all enable.
PIM is enabled on Loopback 0 based on its explicit configuration (interface Loopback0 enable) under router pim configuration mode.
IGMP protocol is enabled on GigabitEthernet0/6/0/3, because it too has been configured explicitly under router igmp configuration mode (interface GigabitEthernet0/6/0/3 router enable):
RP/0/RSP0/CPU0:router(config)# multicast-routing
RP/0/RSP0/CPU0:router(config-mcast)# address-family ipv4

RP/0/RSP0/CPU0:router(config-mcast-default-ipv4)# interface loopback 1 enable
RP/0/RSP0/CPU0:router(config-mcast-default-ipv4)# show run router pim
With the interface-inheritance disable command in use, IGMPand PIM configuration are enabled in the protocol configuration as follows:

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
The mhost default-interface command configures the interface that the automatic route processing (Auto-RP), ping, and mtrace applications use for multicast transmissions, and the interface to which multicast groups are joined for reception.
The ping and mtrace features may use the MHost default interface to process multicast messaging. When IP multicast routing is enabled, packets sent to the MHost default interface are switched on other interfaces with a matching forwarding state. In addition, an arbitrary interface may be chosen to be the active MHost default interface if the configured interface is not operational. If no MHost default interface is configured with this command, an arbitrary interface is selected as the active MHost default.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
The nsf command does not enable or disable the multicast routing system, but just the NSF capability for all the relevant components. When the no form of this command is used, the NSF configuration is returned to its default disabled state.
Enable multicast NSF when you require enhanced availability of multicast forwarding. When enabled, failures of the control-plane multicast routing components Multicast Routing Information Base (MRIB) or Protocol Independent Multicast (PIM) will not cause multicast forwarding to stop. When these components fail or communication with the control plane is otherwise disrupted, existing Multicast Forwarding Information Base (MFIB) entries continue to forward packets until either the control plane recovers or the MFIB NSF timeout expires.
Enable multicast NSF when you upgrade control-plane Cisco IOS XR software packages so that the live upgrade process does not interrupt forwarding.
When the MFIB partner processes enter NSF mode, forwarding on stale (nonupdated) MFIB entries continues as the control-plane components attempt to recover gracefully. Successful NSF recovery is signaled to the Multicast Forwarding Engine (MFWD) partner processes by MRIB. MRIB remains in NSF mode until Internet Group Management Protocol (IGMP) has recovered state from the network and host stack and until PIM has recovered state from the network and IGMP. When both PIM and IGMP have recovered and fully updated the MRIB, MRIB signals the MFIBs that NSF is ending, and begins updating the stale MFIB entries. When all updates have been sent, the MFWD partner processes delete all remaining stale MFIB entries and returns to normal operation, ending the NSF mode. MFIB NSF timeout prior to the signal from MRIB may cause NSF to end, and thus forwarding to stop.
When forwarding is in NSF mode, multicast flows may continue longer than necessary when network conditions change due to multicast routing protocols, unicast routing protocol reachability information, or local sender and receiver changes. The MFWD partner processes halt forwarding on stale MFIB entries when the potential for a multicast loop is detected by receipt of incoming data on a forwarding interface for the matching MFIB entry.
Note
For NSF to operate successfully in your multicast network, you must also enable NSF for the unicast protocols (such as Intermediate System-to-Intermediate System [IS-IS], Open Shortest Path First [OSPF] and Border Gateway Protocol [BGP]) that PIM relies on for Reverse Path Forwarding (RPF) information. See the appropriate configuration modules to learn how to configure NSF for unicast protocols.

Usage Guidelines
TTo use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
MoFRR is a mechanism in which two copies of the same multicast stream flow through disjoint paths in the network. At the point in the network (usually the PE closer to the receivers) where the two streams merge, one of the streams is accepted and forwarded on the downstream links, while the other stream is discarded. When a failure is detected in the primary stream due to a link or node failure in the network, MoFRR instructs the forwarding plane to start accepting packets from the backup stream (which now becomes the primary stream).
MoFRR is triggered when the hardware detects traffic loss on the primary path of a given flow or route. Traffic loss is defined as no data packet having been received for 30 ms. When MoFRR is triggered, the primary and secondary reverse-path forwarding (RPF) interfaces are exposed to the forwarding plane and switchover occurs entirely at the hardware level.
The show mfib hardware route mofrr command displays the output MoFRR route list of the platform. If there is no MoFRR route enabled in the platform, then the output result is "There are no MoFRR routes configured".

Use the show mfib hardware route statistics command to display the hardware packet and byte counter for a route. Route counters are kept for (S, G) routes only. A single set of counters is provided for all
(*, G) routes.
This command displays the hardware packet and bytes count on a per-route basis. Per-route hardware counters are kept for (S, G) routes only. However, counters are managed dynamically and allocated on a priority basis and may not be available for each (S, G) route. There is a single set of counters for all
(*, G) routes. For example, interface counters and access list counters have higher priority than route counters.

The show mfib nsf command displays the current multicast NSF state for the MFIB process contained on all line cards and route processors (RPs) in the router.
For multicast NSF, the state may be one of the following:
•
Normal—Normal operation: The MFIBs in the card contain only up-to-date MFIB entries.
•
Boot Card Booting—Card is initializing and has not yet determined its NSF state.
•
Not Forwarding—Multicast Forwarding Disabled: Multicast routing failed to recover from a failure-induced NSF state prior to the MFIB NSF timeout.
•
Non-stop Forwarding Activated—Multicast NSF active: The router is operating in NSF mode while attempting to recover from a control-plane failure. In this mode, data is forwarded based on MFIB entries that are either updated by the recovered Multicast Routing Information Base (MRIB), or MFIB entries that were marked stale when NSF mode began. The times remaining until multicast NSF and multicast-unicast NSF expiration are displayed.

Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper task IDs. If you suspect user group assignment is preventing you from using a command, contact your AAA administrator.
All entries in the MFIB table are derived from the Multicast Routing Information Base (MRIB). The flags have the same connotation as in the MRIB. The flags determine the forwarding and signaling behavior according to a set of forwarding rules for multicast packets. In addition to the list of interfaces and flags, each route entry shows various counters. Byte count is the number of total bytes forwarded. Packet count is the number of packets received for this entry.
The show mfib counter command displays global counters independent of the routes.
This command displays counters for the number of packets and bytes that are handled by software switching. Counters for packets processed by hardware are displayed by the appropriate show mfib hardware command.
The command displays the cumulative rates per route for all line cards in the Multicast Forwarding Information Base (MFIB) table when the rate keyword is used with the source and group IP addresses.
The command displays the rate per route for one line card in Multicast Forwarding Information Base (MFIB) table when the statistics keyword is used.

If MRIB NSF state is activated, the time remaining until MRIB reverts to Normal mode displays. Before this timeout, MRIB receives notifications from IGMP and PIM, triggering a successful end of NSF and cause the transition to normal state. If notifications are not received, the timer triggers a transition back to normal mode, causing new routes to download to MFIB and old routes to be deleted.

Each line card has an individual Multicast Forwarding Information Base (MFIB) table. The MFIB table maintains a subset of entries and flags updated from MRIB. The flags determine the forwarding and signaling behavior according to a set of forwarding rules for multicast packets. In addition to the list of interfaces and flags, each route entry shows various counters. Byte count is the number of total bytes forwarded. Packet count is the number of packets received for this entry.
The show mfib counter command displays global counters independent of the routes.
