Cisco Bug: CSCuo95449 - Beni: Vrf: ipv6 traffic is getting routed using the global routing table
Jul 12, 2018
- Cisco Catalyst 4000 Series Switches
Known Affected Releases
Symptom: IPv6 only traffic that ingress a 4500X VSS in a VRF is not correctly routed out of the VRF. It gets routed into the global VRF instead. Conditions: 1. The VRF on the incoming interface doesn't have a route to destination IP. 2. Traffic is IPv6 only. 3. For the destination IP, there is a route in the global routing table. The issue does not appear under these conditions. 1. The VRF on the incoming interface has a route to destination IP. Even if global routing table has a route, the VRF route takes precedence. 2. The route to reach destination IP is present in a different VRF than the incoming interface's VRF.
