Have a loop in my OSPF
Have an IP 172.16.6.66/26 that is un-reachable and one hop from core. Ping gives result:

10.0.0.34                                  84  64 11ms  redirect host            
10.0.0.33                                  84  64 14ms  redirect host            
10.0.0.34                                  84  64 42ms  redirect host            
10.0.0.33                                  84  64 58ms  redirect host            
10.0.0.34                                  84  64 123ms redirect host            
10.0.0.33                                  84  64 149ms redirect host            
10.0.0.34                                  84  64 186ms TTL exceeded

Looking at routes on each router, I get the following on core:

25 ADo  172.16.6.64/26                     10.0.0.35               110

And the following on tower:

25 ADC  172.16.6.64/26     172.16.6.65     ether5-users              0

I am setting up MPLS but not sure that really makes a difference in this issue but here is the remote bindings for the subnet in the core:

35  D 172.16.6.64/26                     243           10.255.74.4:0
46 AD 172.16.6.64/26     10.0.0.35       impl-null     10.255.74.5:0

Remote bindings in the tower are:

32 D 172.16.6.64/26 230 10.255.74.2:0

I am not certain where else to look for the culprit in this loop.

Any thoughts?

Thanks in advance

It’s mpls. Stop advertising all links for the time being. Just advertise the loop back.

Have you checked redistribution to ensure that you aren’t having some issues there?

Hello, I have a similar problem if the author theme can suggest how to solve the problem?
