Overview: Configure Multiple Single-Hop EBGP Sessions on Different Links Using the Same Link-Local Address (IPv6)
In complex networks such as Data Center or Cloud, link-local addresses are widely used due to the high number of links and nodes. Being able to deploy multiple single-hop BGP sessions for Juniper devices using link-local addresses is a significant advantage.
Starting in Junos OS Release 20.4R1, you can enable single-hop EBGP sessions on different links over multiple directly connected peers that use the same IPv6 link-local address. You are no longer required to have unique peer addresses for Juniper devices for every EBGP session.
