LSM-MLDP-based MVPN Support

First Published: November 28, 2012

The Label Switched Multicast (LSM) feature supports IPv4 and IPv6 multicast traffic over a Multi-Protocol Label Switching (MPLS) network. This feature is based on the basic MPLS infrastructure and supports IP multicast traffic through the MPLS clouds. The LSM feature enables service providers to extend the existing MPLS backbone network for 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 LSM service includes point-to-multipoint (P2MP) and multipoint-to-multipoint (MP2MP) packet transport. The P2MP packet transport can be implemented using either Resource reSerVation Protocol (RSVP) P2MP - Traffic Engineering (P2MP-TE), or Multicast Label Distribution Protocol (MLDP) based Multicast VPN (MVPN). The MP2MP packet transport can be implemented only through MLDP based MVPN.

The packets are transported over three types of routers:

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

Restrictions and Usage Guidelines

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

  • A head-end router does not support multiple sub Label Switched Paths (subLSPs) belonging to different tunnels, over the same physical interface.
  • RSVP-TE-based LSM is not supported; only MLDP-based LSM is supported.
  • Process-level software forwarding is not supported.
  • Rosen Model MLDP is not supported in the global configuration mode. However, MLDP inband signaling is supported in the global configuration mode.
  • These are the scale considerations for MLDP-based MVPN:

Maximum number of Multicast Virtual Route Forwardings (MVRFs) supported on each PE is 600.

Maximum number of m-route supported on each PE is 200,000.

Maximum number of OIF supported is 1000.

Maximum number of MLDP ingress labels (local labels) supported on each PE is 100,000.

Maximum number of MLDP egress labels (remote labels) supported on each PE is 100,000.

Max of 32 PE or P neighbors in a PE router per MDT, and max of 33 PE or P neighbors in a P router per MDT.

  • 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.
  • The PIM-sparse content group mode is supported if the RP is configured behind the PE router (on CE). The RP and the source router have to be in the same VRF and PE site with the same RPF interface.
  • For RPF lookup in the context of the extranet, only the ip multicast rpf select command is supported for the configuration.
  • The MLDP provides only link protection with the FRR TE. Only single hop is supported with MLDP TE. However, the backup path can have multiple hops.

Configuring LSM-MLDP-based MVPN Support

Deployment of an LSM-MLDP-based MVPN involves configuring a default Multicast Distribution Trees (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 MVPN also supports dynamic creation of data MDTs for high-bandwidth transmissions. For high-rate data sources, a data MDT is created using the P2MP LSPs to offload the traffic from the default MDT to avoid unnecessary wastage of bandwidth to PEs that are not a part of the stream. You can configure MLDP MVPN for both the intranet and the extranet.


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

DETAILED STEPS

 

Command
Purpose

Step 1

enable

 
Router> enable

Enables privileged EXEC mode.

  • Enter your password when prompted.

Step 2

configure terminal

 

Router# configure terminal

Enters global configuration mode.

Step 3

mpls MLDP

 

Router(config)# mpls MLDP

Enables MPLS MLDP support.


Note The mpls MLDP command is configured by default. To disable MPLS MLDP, use the no mpls MLDP command.


Step 4

vrf definition vrf-name

 

Router(config)# ip vrf blue

 

Defines the VPN routing instance by assigning a VRF name, and enters the VRF configuration mode.

The vrf-name argument is the name assigned to a VRF.

Step 5

rd route-distinguisher

 

Router(config-vrf)# rd 10:3

 

Creates routing and forwarding tables. Specify the route-distinguisher argument to add an 8-byte value to create a VPN prefix.

You can enter an route-distinguisher value in either of these formats:

  • 16-bit autonomous system number: Your 16-bit number. For example, 101:3.
  • 32-bit IP address: Your 32-bit number. For example, 192.168.122.15:1.

Step 6

vpn id vpn-id

 

Router(config-vrf)# vpn id 10:3

 

Sets or updates a VPN identifier on a VRF.

Step 7

route-target import route-target-ext-community

 

Router(config-vrf)# route-target import 10:3

 

Creates a route-target extended community for a VRF.

  • The import keyword imports the routing information from the target VPN extended community.
  • The route-target-ext-community argument adds the route-target extended community attributes to the VRF list of import, export, or both (import and export) route-target extended communities.

Step 8

route-target export route-target-ext-community

 

Router(config-vrf)# route-target export 10:3

Router(config-vrf)# mdt default mpls MLDP 2.2.2.2

 

Configures MLDP MDT for a VRF. The root node can be IP address of a loopback or physical interface on any router (source PE, receiver PE or core router) in the provider network. The root node address should be reachable by all the routers in the network. The router from where the signalling occurs functions as the root node.

The default MDT must be configured on each PE router to enable the PE routers to receive multicast traffic for this particular MVRF.


Note By default MPLS MLDP is enabled. To disable, use the no mpls MLDP command.



Note LSPVIF tunnel is created as a result of mdt default mpls MLDP root-node command.


Step 10

mdt data mpls MLDP numberofdataMDTs

 

Router(config-vrf)# mdt data mpls MLDP 100

Configuring MLDP MVPN for Extranet Services

You can configure MLDP MVPN for extranet services using these methods:

  • Source-Side Chaining (SSC): Configure the phantom receiver MVRF on the source-side router. Multicast routes with VRF Reverse Path Forwarding (RPF) loopup should be configured on the source PE.
  • Receiver-Side Chaining (RSC): Configure the phantom source MVRF on the receiver-side router. Multicast routes with VRF RPF loopup should be configured on the receiver VRF.

Configuring MLDP MVPN for Extranet using SSC

Complete these steps to configure the MLDP MVPN extranet support using SSC:

  • Configuring receiver MVRF on the source PE.
  • Configuring a loopback address in the receiver VRF on the source PE.
  • Configuring fallback multicast route for source address on source PE.
  • Configuring fallback multicast route for RP address on the source PE in case of SM mode.
  • Configuring static multicast route on recevier PE for loopback IP in the receiver VRF configured on the source PE.

Note This configuration is based on illustration Figure 20-1. Configure multicast routes on the PE1 router.

Configuring MLDP TE-FRR Support

TE-FRR provides link protection, however TE-FRR on MLDP provides link protection only for the single hop primary path. Node protection is not supported.These are the highlights:

  • Backup tunnel support
  • Backup bandwidth protection

For more information on MPLS TE-FRR, see MPLS Point-to-Multipoint Traffic Engineering .

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 the LSM-MLDP-based MVPN support configuration.

  • To check the MLDP neighbors, use the show mpls MLDP neighbors 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 20-1. Consider these scenarios while configuring MLDP MVPN using SSM mode:

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

MVPN MLDP over GRE

The Multicast Label Distribution Protocol- based Multicast VPN (MVPN) feature supports IPv4 and IPv6 multicast traffic over a Multi-Protocol Label Switching (MPLS) network. But a large part of the network infrastructure is still IP network, and the legacy IP network does not support MPLS. The existing MPLS over Generic Routing Encapsulation (GRE) feature provides a mechanism for tunneling MPLS packets over a non-MPLS network by creating a GRE tunnel across the IP network and bridging the separated MPLS networks. However, the existing MPLS over GRE feature does not support MPLS multicast traffic. The MVPN MLDP over GRE feature provides a solution by supporting encapsulating MPLS multicast traffic in the GRE tunnel.

Figure 20-2 shows a sample configuration for MVPN Multicast Label Distribution Protocol over GRE using the PE-PE network topology.

Figure 20-2 MVPN MLDP over GRE with PE-PE Network Topology

Prerequisites for MVPN MLDP over GRE

  • Ensure that MPLS Virtual Private Network (MVPN) is configured and working properly. For information about setting up MPLS VPNs, see:

http://www.cisco.com/en/US/docs/ios-xml/ios/mp_l3_vpns/configuration/xe-3s/asr1000/mp-cfg-layer3-vpn.html

  • Ensure that Multiprotocol Border Gateway Protocol (MP-BGP) is configured and working properly. For more information about configuring (MP-BGP), see:

http://www.cisco.com/en/US/docs/ios-xml/ios/mp_l3_vpns/configuration/xe-3s/asr1000/mp-bgp-mpls-vpn.html

Restrictions for MVPN MLDP over GRE

The following are the restrictions that you will encounter while configuring the MVPN MLDP over GRE feature:

  • MVPN MLDP over GRE supports only IPv4 GRE.
  • MVPN MLDP over GRE supports IPv4 and IPv6 multicast traffic.
