Feb 14, 2018
- Cisco IOS
Known Affected Releases
Symptoms: Multicast traffic destined for a dialer interface configured with PPPoA is not forwarded, although the counters in the output of the <CmdBold>sh ip mroute count<noCmdBold> command and all multicast state information seems correct. Conditions: This symptom is observed -on a Cisco 1800 series integrated services router (ISR) configured with PPPoA over DSL link while running Cisco IOS Release 12.4(24)T. - when the multicast traffic originates on the LAN and is transmitted over the dialer interface toward the receivers/PIM RP. Initial packets may be correctly sent while the multicast group is in registering state, but once the source is registered with the RP, sending the multicast traffic fails. - CEF is globally enabled on all interfaces.
