BGP configuration error when using remove-private-as
Closed, ResolvedPublicBUG
Actions

Description

There seems to be a bug in VyOS 1.2.2 and 1.2.3-epa1 where you can't set "remove-private-as" because VyOS somehow thinks you are setting up an iBGP session. This bug can be reproduced with a very simple configuration:

set protocols bgp 1000 neighbor 10.0.0.1 remote-as 2000
set protocols bgp 1000 neighbor 10.0.0.1 address-family ipv4-unicast remove-private-as

When you try to commit these commands, you get:

[ protocols bgp 1000 neighbor 10.0.0.1 address-family ipv4-unicast remove-private-as ]
you can't set remove-private-as for an ibgp peer

[[protocols bgp 1000]] failed

It won't even work if you configure a specific local AS for this neighbor:

set protocols bgp 1000 neighbor 10.0.0.1 local-as 1000

If you need more information, let me know.

This is working again in VyOS 1.2.3 GA. I have tested both the simple configuration mentioned above and my actual configuration with a bunch of BGP peers. Thank you very much!
