Hi Roman
Tx for the response. I have verified all the points you mentioned below and
everything seems okay. I do have PE-CE PIM neighborship on both CE routers.
My CE routers are SW1 and SW2 connecting to R3 and R6 respectively.
The PIM mdt bgp output on both R3 and R6 is as
r3(config-if)#do sh ip pim mdt bg
Peer (Route Distinguisher + IPv4) Next Hop
MDT group 232.2.2.2
2:100:1:150.1.6.6 150.1.6.6
r6(config)#do sh ip pim mdt bgp
Peer (Route Distinguisher + IPv4) Next Hop
MDT group 232.2.2.2
2:100:1:150.1.3.3 150.1.3.3
The loopback IPs for these PE routers are 150.1.3.3 and 150.1.6.6.
Throughout the customer carrier network and the backbone carrier network, I
do have PIM neighborship with the next router. I am running PIM-SM mode
throughout the network and one of the CE routers is the BSR.
sw2(config)#do sh ip pim rp map
PIM Group-to-RP Mappings
This system is the Bootstrap Router (v2)
Group(s): 224.0.0.0/4, Static
RP: 150.1.8.8 (?)
sw2(config)#
