Which two statements are true about IP fabrics using unnumbered BGP? (Choose two.)
Suggested Answer: A,B Vote an answer
BGP unnumbered peering uses only link-local IPv6 addresses on interfaces to automatically discover and establish BGP peer sessions. No routable IP addresses are required on the underlay interfaces.
You must configure the interfaces with family inet6 to enable the link-local IPv6 addresses used for peering.
The BGP peering session is dynamically created based on interface names, which simplifies the configuration significantly compared to manual peering with routable IP addresses.
The peer IP and remote AS numbers are automatically configured for BGP unnumbered peering.
This means unnumbered BGP automatically provisions IPv6 peering using the link-local addresses.
It also supports IPv4 route exchange over the IPv6 next-hop established by unnumbered BGP.
