@jhiggins-NZ This sure looks like you have different versions of FRR installed at the same time. Or when you started with a new version you didn't kill off the old one running fully.

Can you make sure that you've (a) killed all the daemons (b) and then installed and finally (c) restarted?

[jhiggins-NZ]

Thanks Donald. I might have forgotten to paste in the stop, daemon reload & start commands from my template.

I'll give it another go later.

[donaldsharp]

As per Lou's Suggestion, we should have a new enhancement to let vtysh notice it is compiled against the wrong version of the daemons currently running.

@jhiggins-NZ have you had a chance to retest?

[jhiggins-NZ]

@donaldsharp yes, running on NZ time. :)

Looks like it is my fault and I forgot to kill the old processes properly.

R1(config)# router bgp
  <cr>
  (1-4294967295)  AS number
R1(config)# router isis
  WORD  ISO Routing area tag
R1(config)# router ospf
  <cr>
  (1-65535)  Instance ID

CLI tests look fine.
