ASA Stops sending OSPF hellos
Wondering if anyone else has come across this problem, but have two Cisco ASA 5510s ASA V7.2(1), DM V5.2(1) (in active/passive failover configuration). These are connected to a pair of 3750G-48-EMIs in a stack, OSPF is running on both, The ASAs are redistributing the outside, and DMZ interfaces by a defined route-map.
Everything normally works fine, but today I found that the neighbour relationship between the ASAs and 3750s had broke. I tried clearing the OSPF process on both the ASAs and 3750, but this would not resolve the problem. The 3750 would not show the ASAs in the neighbour list, but did have other devices (via a point-to-point link) as FULL state. The ASAs however would show the 3750s as INIT/DROTHER state.
Debugs showed that the ASAs were receiving hellos from the 3750s but was not sending any. The 3750s showed it was sending hellos but not receiving any from the ASAs
To resolve I had to reboot the ASAs. This is not my preferred solution as should not need to do this.
Has anyone else come across this problem, and is there a resolution? Or a bug track id?
Thank you in advance for your assistance.
I always rate helpful replies.
Best regards, Adrian
The bug workaround suggests adding static ARP for the neighbor device. Add a static ARP entry for the 3750 on your ASA. The bug only applies to ASA and hence, you shouldn't need a static entry on the 3750.
