Trying to connect dual stack ipv4 and ipv6 bgp sessions. IPv4 connects just fine and establishes bgp. IPv6 connects but does not establish BGP. On the cisco side its receiving “Notification sent (OPEN Message Error/Unsupported Capability)”. I tried disabling and overriding combability but it did not help.
Is this a bug in the software? How can I tell what combabilities are not working?
I found this post in FRR page about the same issue I think.
Any recommendations?
