ESI Status: Unresolved in show evpn instance extensive

‎04-19-2019 02:34 PM

Hello everyone. 

I`m seeing Status: Unresolved on remote PE for multi-homed ESI segment, while in normal situation  i can see something like "Status: Resolved by NH 1048576". Why is it happening?

Hi smelnik,

 

Was there any change that triggered this? Please share full output of "show evpn instance <> extensive".

It seems these routes may not be active on the remote PE. So please check if these routes are actually still active for this ES on the remote PE.

show evpn mac-table 56:68:a6:6b:29:55
or
show route table <evpn_instance_name>.evpn.0 protocol evpn extensive

 

If the MAC route isn't active on the remote PE, but still showing up on other PE's that sounds incorrect and should be reported. Try to toggle the ESI config on the PE where the ES is local and see if this resolves.

 

Hope this helps.

 

Regards,
-r.
