I have a MVPN setup in our lab multicast seems to be working fine on default mdt. However, data MDT does not kick in even though traffic exceeded the threshold which is set to one. I have SSM setup in P and PE routers. For CE is just issued "ip pim sparse-dense-mode" on all eth0 and s0. I didn't specify PIM globally.
PE config:
ip mulitcast-routing
ip multicast-routing vrf red
ip vrf red
mdt default 239.232.0.0
mdt data 239.232.4.0 0.0.0.3 threshold 1
ip pim ssm range MDT-range
ip access-list standard MDT-range
permit 239.232.0.0 0.0.255.255
ip pim sparse-dense-mode (on all participating interfaces)
Turned "debug ip pim" on source PE and it seems the source PE is not even sending a join message to other PEs.
Any help would be much appreciated.
Thank in advance,
John
