Jan 29, 2017
- Cisco IOS
Known Affected Releases
Symptom: can result in dup packets on segment when mcast topo changes in multi-vendor environment. "debug ip pim" will show PIM(0): Received v2 Assert on Vlan1 from 192.168.1.1 PIM(0): Invalid host address 0.0.0.0 Conditions: When another router sends PIM assert with source address 0.0.0.0 and RPT bit set, PIM will reject it as an invalid source. Only happens when forwarding on shared tree as this is the only time per RFC 4601 when assert with source address 0.0.0.0 is valid.
