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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
