I'm sorry about that I did not follow up on this problem. IP LFA is not supported on VLAN interfaces (at least not on 15.3(3)S4) Bug: Whenever IP LFA is used and a backup path is computed via VLAN interface HW forwarding gets corrupted on the box. You are "lucky" though, as when we ran into this the box stopped forwarding all transit traffic (only traffic to the box was not affected fortunately)
The workaround is to never use VLAN interfaces with IP FRR. So would you please try shutting down the VLAN36 interface if it helps (provided there are no other VLAN interfaces that can be used as LFA backup link)? > ME02: > #sh ip cef xxx.xxx.xxx.222/32 detail > xxx.xxx.xxx.222/32, epoch 0 > local label info: global/20625 > 2 RR sources [heavily shared] > nexthop xxx.xxx.xxx.232 GigabitEthernet0/3 label [none|674] > repair: attached-nexthop xxx.xxx.xxx.234 Vlan36 <========== > nexthop xxx.xxx.xxx.234 Vlan36, repair <======= > adam --------------------------------------------------------------------------------------- This email has been scanned for email related threats and delivered safely by Mimecast.
