Statement introduced before Junos OS Release 10.2 for J-EX Series switches.
Configure an EBGP multihop session.
External confederation peering is a special case that allows unconnected third-party
next hops. You do not need to configure multihop sessions explicitly in this particular
case; multihop behavior is implied.
If you have confederation external BGP peer-to-loopback addresses, you still need the
multihop configuration.
If you omit this statement, all EBGP peers are assumed to be directly connected (that
is, you are establishing a nonmultihop, or "regular," BGP session), and the default
time-to-live (TTL) value is 1.
