ASA Losing Connected Routes?

andrew8989

Level 1

Recently updated from 9.12.4 to 9.14.4 on a 5525-X with no FTD or FMC. We have a IPSEC tunnel with a VTI to another site but about once a week the ASA will lose the /30 connected route between the 2 VTIs even though both tunnel phases are up. This is a big problem due to the VTIs on both sides being neighbor addresses for a private BGP network. The current work around is shutting the VTI and bringing it back up after which the route is reinstalled. 

I'm at a loss on why this thing is losing a connected route. I've never heard of this.

Does this happen after tunnel flap? Did you try to analyze syslogs for the period?

I mean, this is definitely a bug and only TAC will be able to fix it, but you may try to prevent tunnel flapping if you understand why it happens, or at least you can try to confirm this theory and this will in turn help TAC later on.
