Going from SRD6 to SRE6 on a 7600 caused changing the multicast replication mode from egress to ingress. It seems that in SRD6 the supervisor - which is a SUP720 - automatically detected the replication mode based on the module types installed in the system - and set the replication mode to egress. After going to SRE6, we noticed that a new command appeared in config: mls ip multicast replication-mode ingress and because of this the replication mode is now ingress even all the modules are egress capable: #show platform software multicast ip capability Current System HW Replication Mode : Ingress Auto-detection of Replication Mode : OFF Slot Replication-Capability Replication-Mode 1 Egress Ingress 2 Egress Ingress 3 Egress Ingress 4 Egress Ingress 5 Egress Ingress 9 Egress Ingress SRD6: ! ip multicast-routing ip multicast multipath s-g-hash next-hop-based SRE6: ! ip multicast-routing mls ip multicast replication-mode ingress ip multicast multipath s-g-hash next-hop-based Did someone else notice this (strange?) behavior?
