seconds for an EBGP peer.
Enabling BGP to establish an EBGP session over multiple hops
To establish an EBGP connection, two routers must have a direct physical link. If no direct link is available,
you must use the
peer
ebgp-max-hop
command to enable BGP to establish an EBGP session over
multiple hops and specify the maximum hops.
If directly connected EBGP peers use loopback interfaces to establish a BGP session, you do not need to
configure the
peer ebgp-max-hop
command.
When the BGP GTSM function is enabled, two peers can establish an EBGP session after passing GTSM
check, regardless of whether the maximum number of hops is reached.
To enable BGP to establish an indirect EBGP session (IPv4 unicast/multicast address family):
