Support for BGP Auto-discovered Neighbor (MX Series, PTX1000, PTX10008, QFX5120-32C, QFX5200, QFX5210, and QFX10008)—Starting in Junos OS Release 21.1R1, we support BGP auto-discovered neighbors using IPv6 Neighbor Discovery Protocol (ND). With this feature, you can enable BGP to create peer neighbor sessions using link-local IPv6 addresses of directly connected neighbor devices. You need not specify remote or local neighbor IP addresses.
To enable peering for a given interface or set of interfaces without specifying the local or remote neighbor addresses, configure the
peer-auto-discovery
statement at the [edit fabric protocols bgp group <name> dynamic-neighbor <name>
] hierarchy level.[ See BGP Auto-Discovered Neighbors, and peer-auto-discovery.]
