In this post I will talk about VPN Multicast, Rosen draft. It will cover basic configuration VPN multicast. The topology of this test is similar with the previous post PIM-SM. In order to simulate the multicast under VRF, there is additional CE router behind the PEs (R1, R5 and R5). There are 2 RPs set, C-RP and S-RP. Multicast VPN draft Rosen having some constraints such as Core must have PIM-SM with RP, no TE support, etc. You can see the complete configuration at the end of this post.
C-RP belongs to VRF and S-RP belongs to service provider. Multicast tunnel are needed on each PE and RP, you must have Tunnel PIC or another service PIC to support this MT interface. MT interface will setup automatically when you configure MDT (vpn-group-address).
C-RP IP address is 10.10.10.10 which is IP address of Lo0 VRF on R1. S-RP is 10.0.3.5.
CE1 and CE2 will have static routes to R1 and R5. CE3 will use BGP to connect to R6.
VRF name on R1 is rosen-1, R2 is rosen-2 and R3 is rosen-3
The configuration is quite similar with Multicast PIM-SM except VRF configuration. You will need to configure secondary loopback for each PE inside VRF like show below:
enugadi@M7i# show interfaces lo0
unit 0 {
family inet {
address 10.0.6.1/32 {
primary;
}
}
family iso {
address 49.0001.1111.1111.1111.00;
}
}
unit 14 {
family inet {
address 10.10.10.10/32;
}
}
Lo0.14 will used as VRF’s Lo0.
Below is the VRF configuration on R1:
rosen-1 {
instance-type vrf;
interface lo0.14;
interface vt-1/2/0.0;
interface ge-0/0/1.24;
vrf-target target:65412:1;
routing-options {
static {
route 10.0.5.0/24 next-hop 172.16.40.2;
route 11.11.11.11/32 next-hop 172.16.40.2;
}
}
protocols {
pim {
vpn-group-address 225.0.0.0;
rp {
local {
address 10.10.10.10;
}
}
interface all {
mode sparse;
}
interface lo0.14 {
mode sparse;
}
}
}
}
Multicast sender 10.0.5.200 will send multicast data to CE1:

Hello Nugroho,
Very interesting article.
However based on your logical router config I found a gap between your network map and the “real topology”. For instance R6 and R5 are not connected. The actual topology is a tree.
I can send it a JPEG file of the topology based on your configuration file if you are interested.
Regards, Didier
Hi Didier… sorry I haven’t check this blog for a long time. I’m tied up with another things here
Sure, please send the the topology and I’m interest for some discussing
