Use multicast-domain to create an MD for a VPN instance and enter MD view. Use undo multicast-domain to clear the configurations that are made in MD view for a VPN instance. Multicast-domain vpn-instance vpn-instance-name. Undo multicast-domain vpn-instance vpn-instance-name. No MD exists for a VPN instance.

Hello everyone,

We are having trouble getting MVPN working correctly. Before I get into the specifics of what we have tried and what trouble shooting we have done, here is the setup:

Project description:

• Implement multicast in MPLS L3 VPN

• Partitioned MDT, mLDP MP2MP, PIM C-mcast signaling

Network core:

• Core routers are all Cisco ASR 9Ks running IOS-XR 5.3.3

• IGP is OSPF in global routing space

• MPLS is enabled between all routers

• Full-mesh iBGP - peering with loopbacks (Loopback0, carried in OSPF)

CE devices:

• Site A (SW1) = Cisco 3750x (WS-C3750X-24T-E) running c3750e-universalk9-mz.150-2.SE10a

• Site B (SW2) = Cisco 3750 (WS-C3750G-24TS-E) running c3750-ipservicesk9-mz.122-55.SE9

• Site C (SW3) = Cisco 3750 (WS-C3750G-24TS-E) running c3750-ipservicesk9-mz.122-55.SE9

• Site D (SW4) = Cisco 6509 (WS-C6509-E) running s72033-advipservicesk9_wan-mz.122-33.SXJ5

Note:

Direct link between R1 and R5 is a leased circuit and has the cost set high so that no traffic actually uses that path during normal operations.

Huawei Ma5800 Configuration Guide

We have dedicated a VRF for this multicast traffic and have the unicast portion working. Here is a snippet of the relevant configs on the P/PE routers:

System View Command

R1, R2, R3, R5 (PE Routers):

R4 (P router):

Relevant configs on the CE switches:

SW1, SW2, SW3, SW4:

The sources are video/audio streams. We are able to successfully join and receive the streams sourced via SW1 [ (192.168.80.6,239.0.1.7) and (192.168.80.6,239.0.1.8) ] on a receiver attached to SW4 (via R5). However, we are not able to join/receive any groups via either R2 or R3 (R4 is purely pass-through; no receivers or sources).

These show commands are with an active source at 192.168.80.6 (group 239.0.1.7) and active receivers via R1 and R3.

R1 (connected to SW1 - the RP):

R3 (non-working receiver):

R5 (working receiver):

We have tried removing the egress port on R5 from pim and shutting down the receiver on SW4 to see if that would allow the receiver on SW3 (R3) to successfully join the group, but it did not work. We also looked into MTU on all interfaces, but do not think there is any issue in that regard. I also want to mention that we did use this cisco document to assist with the configuration of the core routers.

Do any of you have any experience with setting this up that might be able to help point us in the right direction? Any and all help would be immensely appreciated. Let me know if you need some specific 'show command' output and I will gladly provide it.
