When a Cisco router is acting as the DR (Designated Router) with spt-switchover enabled, the Cisco router
may erroneously send (S,G) prunes to the OmniSwitch 7700/7800’s causing the multicast streams to be
disrupted. This seems to be the case when the route to the RP is the same as the route to the source.
Workaround: Disable spt-switchover on the Cisco.

On an OS7000 series switch, the console may scroll the following messages to report that there is some-
thing misconfigured or software/hardware is behaving improperly in the lower layers:
tPimsm: Received Hello from my own IP: xx.xx.xx.xx. Invalid configuration
tDvmrp: dvmrpRecvProbe: Configuration/Lower-layer problem V<vlan> Looping back our Probes
tDvmrp: dvmrpRecvReport: Configuration/Lower-layer problem V<vlan> Looping back our own RRs
Workaround: There is no known workaround at this time.
PR 75062
When running in a mixed environment consisting of OS7000's and Cisco's, the OS7000 PIM-SM router
may get into a state in which the flows get disrupted. This is caused by erroneous prunes. Once in this
state, the flows will have to be completely timed out.
Workaround: There is no known workaround at this time.
PR 77055
On an OS7000 series switch, if there are multiple routes to either the RP or any of the multicast sources,
PIM-SM must be enabled on all of the interfaces.
Workaround: Enable PIM-SM on all interfaces that may be considered possible routes to either the Rp or
any of the multicast sources.

IXIA automation tests consisting of 1023 flows and 1023 group memberships can result in IPMRM error
messages scrolling on the console, when the RP is manually deleted and then added again (using the ip
pimsm crp-address command).
Workaround: Set 'ip mroute debug-level 0' so that the messages don't appear on the console.
PR 92679
Using Static-RP Configuration and then changing the max-rps may cause tpimsm to suspend.
Workaround: If using static-rp configuration, the max-rps needs to be configured before defining/
enabling any of the static-rp set.
