hi Phil, because R2 is not part of the NEW TOPOLOGY, R1 and R2 are not PIM neighbors anymore.
[...] R1#sh run | inc ^ip (pim|multi) ip multicast-routing ip multicast-routing vrf XXX ip pim ssm range multicast-mdt R1#sh run int Vlan10 interface Vlan10 description XXX mtu 9216 ip address XXX no ip redirects no ip unreachables no ip proxy-arp ip mtu 1524 ip pim sparse-mode load-interval 30 mpls mtu 1542 mpls ip end ------------ R2#sh run | inc ^ip (pim|multi) ip multicast-routing ip pim ssm range multicast-mdt R2#sh run int Vlan10 interface Vlan10 description XXX mtu 9216 ip address XXX no ip redirects no ip unreachables no ip proxy-arp ip mtu 1524 ip pim sparse-mode load-interval 30 mpls mtu 1542 mpls ip end [...] i issue the command "mls ip multicast" AGAIN on R2 and it looks like this solved my problem.
