Description

MVPN Ingress Replication (IR) over SRv6

Cisco IOS XE 17.18.1a

This feature enables the transport of IPv4 Multicast traffic across an SRv6 network. It simplifies multicast deployment by using the existing SRv6 unicast infrastructure as the underlay. With this feature, the ingress PE router receives multicast traffic and creates a separate unicast SRv6-encapsulated copy for each egress PE router in the multicast group.

MVPN Ingress Replication over SRv6

This document describes MVPN Ingress Replication (IR) over SRv6, a feature that

  • enables the transport of IPv4 Multicast traffic across an SRv6 network,

  • leverages the existing SRv6 unicast infrastructure

  • simplifies multicast deployment by using SRv6 as the underlay transport.

The ingress PE router receives multicast traffic and creates a separate unicast SRv6-encapsulated copy for each egress PE router in the multicast group.

  • Each packet is encapsulated using an SRv6 encapsulation that guides it to the intended egress PE.

  • The core network simply forwards these SRv6 packets based on their segment routing headers; no multicast state is maintained in the core.

  • The egress PE receives and decapsulates the outer SRv6 encapsulation, and then forwards the multicast data in corresponding VPN.

How MVPN Ingress Replication over SRv6 works

This feature primarily supports IPv4 MVPN over an SRv6 network, specifically implementing the SRv6 End.DTMC4 behavior. Key capabilities and benefits include:

Summary

The key components involved in the MVPN Ingress Replication over SRv6 process are:

  • Ingress CE: The customer edge device that faces the multicast source.

  • Ingress PE: The provider edge router that receives multicast traffic, performs replication, and encapsulates it.

  • Core Network (P routers): The underlying SRv6 fabric that forwards encapsulated packets without maintaining multicast state.

  • Egress PE: The provider edge router that receives and decapsulates multicast traffic for receivers.

  • Egress CE: The customer edge device that faces the multicast receiver.

MVPN Ingress Replication over SRv6 describes the end-to-end flow of IPv4 multicast traffic from source to receiver using SRv6 as the underlay, leveraging ingress replication at the PE routers.

Workflow

The MVPN Ingress Replication over SRv6 process involves the following stages:

  1. The ingress CE faces the multicast source and forwards the multicast traffic to the Ingress PE. The Ingress PE performs replication based on learned multicast routes and encapsulates each replica in an IPv6 header. The Egress PE allocates a SID for MVPN per VRF, and the Ingress PE uses that SID for all multicast routes in the VRF for forwarding in the underlay. Each IPv6 packet is then forwarded to the appropriate Egress PE.
  2. The Egress PE receives the unicast IPv6 packet destined for its locally allocated SRv6 SID, decapsulates the outer SRv6 header, and performs a multicast lookup in the associated VRF. The payload is then delivered to the Egress CE facing the multicast receiver.
  3. The Provider Edge (PE) and Provider (P) routers form the SRv6 fabric, while PE devices act as SRv6 edge nodes.

Partitioned MDT profiles

In a partitioned MDT profile, only those egress PE routers with interested receivers are associated with that ingress PE. By using Partitioned MDT we limit the replication state in the Ingress PE to only include Egress PEs that contain receivers.

When a Partitioned MDT profile is used in PE-PE IR, egress PEs may need to identify traffic from ingress PEs, which uses an internal RPF-ID.

Configure MVPN ingress replication over SRv6

Enable MVPN Ingress Replication over SRv6 for the specified VRF, allowing multicast traffic transport over the SRv6 underlay.

SRv6 MVPN IR transports only IPv4 multicast traffic over an SRv6 network. Intra-as BGP auto-discovery for SRv6 and C-mroute overlay signalling are enabled by default. Strict RPF check is also enabled by default.

Before you begin

For more information on static RP and Auto RP configuration, refer Configuring Basic IP Multicast

Follow these steps to configure MVPN IR over SRv6.

Procedure

Step 1

Access the VRF definition configuration mode.

Example:

vrf definition BLUE

Step 2

Enter the address-family configuration mode for IPv4.

Example:

address-family ipv4

Step 3

Configure SRv6 multicast ingress replication.

Example:

srv6-mcast ingress-replication partitioned [data]

  • partitioned: Specifies partitioned MDT.

  • data: Specifies data MDT.

MVPN Ingress Replication over SRv6 is configured for the specified VRF, enabling multicast traffic transport over the SRv6 underlay.

Configure SRv6 MVPN multicast

To enable MVPN Ingress Replication over SRv6 for multicast traffic within a VRF.

Intra-as BGP auto-discovery for SRv6 and C-mroute overlay signaling are enabled by default. Strict RPF check is also enabled by default.

Before you begin

Follow these steps to enable MVPN Ingress Replication over SRv6 for multicast traffic within a VRF.

Procedure

Step 1

Enter the global configuration mode and access the VRF definition:

Example:

vrf definition <vrf-name>

Step 2

Configure the Route Distinguisher (RD) for the VRF.

Example:

rd <route-distinguisher>

Step 3

For IPv4 multicast, enter the address-family.

Example:

address-family ipv4

Step 4

Configure the route-target for the VRF's address-family.

Example:

route-target {import | export | both } <route-target-ext-community>

Step 5

Enable SRv6 multicast ingress replication:

Example:

srv6-mcast ingress-replication partitioned [data]

Step 6

Exit the IPv4 address-family configuration mode:

Example:

exit-address-family

The specified VRF is configured to use SRv6 for MVPN Ingress Replication.

Configure BGP MVPNv4 neighbor encapsulation

To specify the encapsulation type for MVPNv4 updates advertised to a BGP neighbor.

Before you begin

Follow these steps to specify the encapsulation type for MVPNv4 updates advertised to a BGP neighbor.

Procedure

Step 1

Enter the global configuration mode and access the BGP router configuration.

Example:

router bgp <autonomous-system-number>

Step 2

Enter the IPv4 MVPN address-family configuration mode.

Example:

address-family ipv4 mvpn

Step 3

Configure the encapsulation option for a specific neighbor.

Example:

address-family ipv4 mvpn
            neighbor <neighbor-address> activate
            neighbor <neighbor-address> send-community both

The BGP neighbor is configured to advertise MVPNv4 updates only for the specified encapsulation type.

BGP SRv6 configuration

To illustrate a sample BGP configuration for SRv6 in a multicast environment.

This example displays a BGP configuration that

  • includes SRv6 locator and

  • allocation mode settings, which are utilized by Multicast.

router bgp <autonomous-system-number>
          neighbor <neighbor-address> remote-as <remote-as-number>
          neighbor <neighbor-address> update-source <interface-type-and-number>
          segment-routing srv6
          locator <locator-name>
          exit-srv6
          address-family vpnv4 
          neighbor <neighbor-address> activate
          neighbor <neighbor-address> send-community both
          segment-routing srv6
          locator <locator-name>
          alloc-mode per-vrf
          exit-srv6
