IPX Vol 1 - Lab 24 - Multicast VPN

[DOC CD REF] ** This is a good review of Multicast VPN

Note: Referring to the Doc CD, in the IOS I'm currently using (12.4(20T)), it's required that under BGP, I have to configure BGP MDT SAFI, activate neighbors and send-community.

Excerpt:

Configuring the MDT Address Family in BGP for Multicast VPN

Perform this task to configure an MDT address family session on PE routers to establish MDT peering sessions for MVPN.

The mdt keyword has been added to the address-family ipv4 command to configure an MDT address-family session. MDT address-family sessions are used to pass the source PE address and MDT group address to PIM using Border Gateway Protocol (BGP) MDT Subaddress Family Identifier (SAFI) updates.

Config:

router bgp 256

no bgp default ipv4-unicast

bgp log-neighbor-changes

neighbor 200.0.0.5 remote-as 256

neighbor 200.0.0.5 update-source Loopback0

Task 24.9 - Configure PIM sparse-mode on PE to PE links and loopbacks, configure SSM for multicast range 239.1.1.0 to 239.1.1.255, configure PIM spare-dense on VPN facing interfaces.

Task 24.10 - Enable VPNA for Multicast Routing... configure a default MDT and configure an RP address

Notes:

Here you have enable multicast for the VRF under multicast and enable MDT (multicast distribution tree) under the VRF. Finally, for a specific VRF you can specify the rp-address.

Config:

R2#Sh run | i multicast

ip multicast-routing

ip multicast-routing vrf VPNA

R2#

ip vrf VPNA

rd 256:1

route-target export 256:1

route-target import 256:1

R2#sh run | sec rp-address

ip pim vrf VPNA rp-address 200.0.0.4

Task 24.11 - Configure PIM Sparse-Dense on SP facing interfaces on R1..., configure R1 to be a member of group 239.2.2.1...

Notes:

This is basic Multicast configurations.

Config:
