PIM in ROSv7 on CRS3xx

RouterOS Forwarding Protocols
1

has anyone succesfully deployed PIM-SM for IPv6 (or dual-stack) on ROS v7 on CRS3xx devices (particularly CRS309 and CRS312) with L3HW enabled, and ended up with a functional unicast and multicast network?

if so, could you please show a sample configuration?

i have been having a lot of issues with this, ranging from PIM apparently not working at all, or not coming up or flapping for no apparent reason, to PIM completely breaking the router (requiring a reboot). before i spend any more time investigating this or dealing with support, i’m wondering if this feature is working at all in v7.

There was an update to PIM in 7.12beta7 about stability.


*) pimsm - improved system stability;

Might be worth mentioning that PIM-SM isn’t listed as functional in the Routing Protocol Overview page. Status is “initial support”

It is working with this config, but perhaps not ready for production at scale:
