Troubleshooting LSM MLDP based MVPN Support

Label Switched Multicast (LSM) Multicast Label Distribution Protocol (MLDP) based Multicast VPN (MVPN) Support

The Label Switched Multicast (LSM) feature enables service providers to extend the existing IPv4 MPLS backbone network for IPv4 multicast services. By default, MPLS creates an out-label for an in-label for each packet. This feature extends this functionality to create multiple out-labels for a single in-label. The IPv4 Multicast service includes point-to-multipoint (P2MP) and multipoint-to-multipoint (M2M) packet transport. The P2MP packet transport is implemented using Resource Reservation Protocol (RSVP) P2MP – Traffic Engineering (P2MP-TE) and M2M packet transport is implemented through IPv4 Multicast VPN (MVPN) using multicast Label Distribution Protocol (MLDP). The packet are transported over three types of routers:

  • Headend router: Encapsulates the IP packet with one or more labels.
  • Midpoint router: Replaces the in-label with an out-label.
  • Tailend router: Removes the label from the packet.

LSM is implemented on systems based on EARL 7 or EARL 7.5 versions, which support two modes of multicast replication—ingress and egress. The ingress card performs the replication in case of ingress mode and the multicast traffic throughput is limited to 20 Gb/s. The egress replication mode uses the replication capability of fabric to deliver a copy of a packet to each line card. Distributing the replication process across multiple line cards significantly improves the system throughput. On the Cisco 7600 Series Routers, LSM is implemented in the egress mode .


Note LSM MLDP-based MVPN feature is supported on ES+ and ES20 line cards and these supervisors: RSP720, SUP720, and RSP720-10GE. MLDP is supported on all the egress replication capable line cards.


For more information on RSVP P2MP-TE, see http://www.cisco.com/en/US/docs/ios/mpls/configuration/guide/mp_te_p2mp.html

Configuring MLDP MVPN

The MLDP MVPN configuration enables IPv4 multicast packet delivery using MPLS. This configuration uses MPLS labels to construct default and data Multicast Distribution Trees (MDTs). The MPLS replication is used as a forwarding mechanism in the core network. For MLDP MVPN configuration to work, ensure that the global MPLS MLDP configuration is enabled.

To configure MVPN extranet support, configure the source multicast VPN Routing and Forwarding (mVRF) on the receiver Provider Edge (PE) router or configure the receiver mVRF on the source PE. MLDP MVPN is supported for both intranet and extranet.

Figure 51-1 shows MLDP based MVPN network.

Figure 51-1 MLDP Based MVPN Network

 

Packet Flow in MLDP-based MVPN Network

For each packet coming in, MPLS creates multiple out-labels. Packets from the source network are replicated along the path to the receiver network. The CE1 router sends out the native IP multicast traffic. The PE1 router imposes a label on the incoming multicast packet and replicates the labeled packet towards the MPLS core network. When the packet reaches the core router (P), the packet is replicated with the appropriate labels for the MP2MP default MDT or the P2MP data MDT and transported to all the egress PEs. Once the packet reaches the egress PE, the label is removed and the IP multicast packet is replicated onto the VRF interface.

Restrictions and Usage Guidelines

Follow these restrictions and usage guidelines while configuring LSM MLDP based MVPN support:

  • MLDP is supported only in the egress replication mode.
  • A headend router does not support multiple sub Label Switched Paths (subLSPs) belonging to different tunnels, over the same physical interface.
  • NAT with P2MP TE is not supported.
  • Process level software forwarding is not supported.
  • MLDP-based MVPN is not supported for global IPv4 multicast.
  • These are the scale considerations for MLDP based MVPN:

Maximum number of mVRFs supported is 100.

Maximum number of multicast routes supported in each MVRF is 100.

  • Extranet content group mode should be consistent across all the VRFs. These are the valid content group modes: Supported, Unsupported, and PM-sparse mode.
  • Supported content group modes are Protocol Independent Multicast (PIM) sparse mode (PIM-SM) and Source Specific Multicast (SSM) traffic.
  • Unsupported content group modes are PIM dense mode (PIM-DM) and bidirectional PIM (bidir-PIM) traffic.
  • PIM-sparse content group mode is supported if the RP is configured behind the PE router (on CE).
  • Only the static multicast route with fallback-lookup option is supported for RPF lookup for extranet.
  • MLDP provides only link protection with the FRR TE. Only single hop is supported with MLDP TE, the backup path can have multiple hops.

Configuring Label Switched Multicast on 7600

Deployment of an LSM MLDP-based MVPN involves configuring a default MDT and one or more data MDTs.

A static default MDT is established for each multicast domain. The default MDT defines the path used by PE routers to send multicast data and control messages to other PE routers in the multicast domain. A default MDT is created in the core network using a single MP2MP LSP.

An MLDP based MLDP-based MVPN also supports dynamic creation of the data MDTs for high-bandwidth transmission. For high-rate data sources, a data MDT is created using the P2MP LSPs to off-load the traffic from the default MDT to avoid unnecessary waste of bandwidth to PEs that are not part of the stream. You can configure MLDP MVPN for both the intranet or extranet.


Note Before configuring MLDP based MVPN, ensure that the MPLS is enabled on the core facing interface. For information in MPLS configuration, see the Cisco IOS Multiprotocol Label Switching Configuration Guide. Also, ensure that BGP and any interior gateway protocol (OSPF or ISIS) is enabled on the core router.

Configuring MLDP with PIM-based MVPN

MLDP with PIM-based MVPN supports MLDP coexistence with a PIM-based MVPN deployment. Using this feature, you can gradually introduce MLDP in an existing PIM-based MVPN environment, facilitating phased migration towards a complete LSM-based MVPN network infrastructure. If both the MLDP-based MVPN and GRE-based MVPN are configured, MDT selects PIM based MVPN by default. Configure the precedence for MLDP MVPN and PIM based MVPN using the mdt preference option1 option2 command. This example sets MLDP MVPN precedence over PIM based MVPN:

Router(config-vrf)# mdt preference mldp pim

 

MLDP Support with Load Balancing

MLDP supports load balancing of multicast traffic with Equal Cost Multipath (ECMP) links. For Load balancing to work with MLDP, use the disable mpls mldp forwarding recursive command, which is enabled by default. Also, ensure that the mpls mldp path multipath command is enabled for load balancing to function as expected.

Root Node Redundancy

Configure multiple root nodes in the network using the mdt default mpls mldp ip_address command. The control plane builds a corresponding tree with root at the configured node to enable efficient forwarding. A node in the network selects the nearest root for optimal bandwidth usage. Also, in case a root node is unreachable (due to link failure, or router crash), the node switches to the next available root.

This example describes the root node redundancy configuration:

Router(config)# ip vrf blue1
Router(config-if)# rd 10:3
Router(config-if)# vpn id 10:3
Router(config-vrf)# route-target import 10:3
Router(config-vrf)# route-target export 10:3
Router(config-vrf)# mdt default mpls mldp 2.2.2.2
Router(config-vrf)# mdt default mpls mldp 5.5.5.5

Verification

Use these commands to verify LSM MLDP based MVPN support configuration:

  • To check the MLDP neighbors, use the show mpls mldp neighbor command:

Sample Configuration for MLDP MVPN

You can configure MLDP MVPN in these two modes:

  • Source Specific Mode (SSM)
  • Sparse Mode (SM)

Configuration Example Using SSM mode

These examples are based on the topology shown in Figure 51-1. Consider these scenarios while configuring MLDP MVPN using SSM mode:

  • MLDP MVPN Extranet SSC
  • MLDP MVPN Extranet RSC
  • MLDP MVPN Intranet
