I tried the following simple topology for mVPN-
CE1 is connected to the source and CE2 has the receiver.
PE1 & PE3 VRF configuration-
ip vrf CUST1
route-target both 1:1
bgp next-hop Loopback 0
mdt default 188.8.131.52
mdt data 184.108.40.206 0.0.0.15 threshold 1 list 100
access-list 100 permit ip any any
I could send the multicast traffic from one end to another using the Default-MDT. PIM adjacency is formed over the MTI Tunnel 0.
The issue is- no matter how much multicast traffic is sent across (multicast traffic here is large ping packets), PE3 does not switchover to Data-MDT.
Please share your thoughts.
