[BUG] IBGP local-as might not work on Aruba CX #1146

Closed ipspace closed 2 months ago

ipspace commented 2 months ago

When testing neighbor local-as functionality that would result in an IBGP session on Aruba CX, the neighbor on the Cumulus Linux side is in the idle state. It might be easiest to give up and say "we don't do that" ;)

Test topology: https://github.com/ipspace/netlab/blob/dev/tests/integration/bgp/08-ibgp-localas.yml
Validation results: https://tests.netlab.tools/arubacx/libvirt/bgp/08-ibgp-localas.yml-validate.log

You are right, that's not supported on AOS CX.

Also, the "template" is aware of that to avoid failures:

https://github.com/ipspace/netlab/blob/33e49c79f87a4966f3ed2f989b71019272ef9147/netsim/ansible/templates/bgp/arubacx.macro.j2#L12

Will try to report the "error" as a device quirk (in a similar way for what you did in #1152 )

No wait the mistake is even before... ;) I declared local_as_ibgp: true on the device yaml... :|
