fault F1425 on Spine

Hi,
I just mounted my second pod, everything went well except an error F1425 on one of my spines. I did decommission and regiter but still the same error: two loopback interfaces with the same ip address. Any idea?

Hello,

 

Please check if subnets for old and new pod not overlapping.

Hi Pavel,

Both looback interfaces are on this spine (same spine)..

The Cisco ACI fault code F1425 is triggered in any of the following condition:

  • When the IPv4 address state changes to subnet-overlap.
  • When no primary, or if the address is already set as the next hop in a static route.

To resolve this issue, you can attempt the following actions:

  • Check for configuration issues
  • Verify the configuration is correct and complete
  • If the interface is down, fix connectivity or configuration to bring the interface state back up

Hi @conf-t ,

Check that the Pod2 TEP Pool defined in Tenant infra/Fabric Ext Connection Policy does not overlap with the Router-ID/Loopback of that node defined in Tenant infra/L3Outs/MPod/Logical Node Profiles.
