Can anyone tell me what this means? I am having a hard time finding any documentation on it.

Hello Vblaha,

you may need a neigh x:x:X activate in address-family IPv6 unicast on the other device.

that no neg may mean no negotiate or no neighbor

verify also if your local node can reach the BGP endpoint.

Hope to help

Giuseppe

It means that your router is advertising a capability that the peer is not configured for. Think it's usually to do with ipv4/ipv6 address family advertisements.
