A: Multipath load balancing (ECMP) to multiple AS numbers enables fast fail-over by allowing the RIB to install multiple next hops that point to these different AS numbers. Adding support for extended IPv4 nexthops allows IPv4 route exchange over the IPv6 BGP sessions. https://www.juniper.net/documentation/us/en/software/nce/nce-225-bgp-unnumbered/topics/example/nce-225_bgp_unnumbered-example.html#:~:text=Multipath%20load%20balancing%20(ECMP)%20to,over%20the%20IPv6%20BGP%20sessions.
