Subject: [PATCH] Add ipv6 unicast to ExaBGP neighbor family
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The IOS-XR routers negotiate IPv6 unicast capability, but the generated
exabgp.conf declared only ipv4 unicast — producing repeated "route family
(ipv6/unicast) is not configured" errors that crashed ExaBGP. Declaring
ipv6 unicast on the neighbor matches the routers' capabilities and stops
the crash-restart cycle.
