Description |
| Headline: N9500-R/N3600 break link-local control-plane adj for connected L3 devices Symptoms: N9500-R/N3600 running 9.3.8 version of code breaks link-local control-plane adjacencies (e.g. OSPF) for connected L3 devices. When igmp snooping is disabled, link-local control-plane works but this prevents multicast traffic to be forwarded as pim cannot be enabled on SVI with disabled igmp snooping for respective vlan. |
