Preface

Routing verifications


If you have ever tried troubleshooting a routing issue on a different platform, such as IOS, you'll find that verifying routing within the ACI fabric is not much different. We need to remember that we are dealing with VRFs, more than we might normally do, but this is where the context-sensitive help comes into play.

How to do it...

  1. Taking OSPF as the example, we can look at the neighbors for a particular VRF using the show ip ospf neighbors vrf <vrf-name> command or all of the neighbors using show ip ospf neighbors vrf all.
  2. Similarly, we can look at the OSPF routes using show ip ospf route vrf <vrf-name> or show ip ospf route vrf all.
