3. Configure the interval for
sending updates for the
same route to a peer or peer
group.
peer
{ group-name | ipv6-address
[ prefix-length ] }

interval
By default, the interval is 15
seconds for an IBGP peer and 30
seconds for an EBGP peer.
Enabling BGP to establish an EBGP session over multiple
hops
To establish an EBGP session, two routers must have a direct physical link and use directly
connected interfaces. 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.
When the BGP GTSM feature 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):
1. Enter system view.

3. Enable BGP to establish an
EBGP session to an
indirectly connected peer or
peer group and specify the
maximum hop count.
peer
{ group-name | ipv4-address
[ mask-length ] }
ebgp-max-hop
[ hop-count ]
By default, BGP cannot establish
an EBGP session to an indirectly
connected peer or peer group.
To enable BGP to establish an indirect EBGP session (IPv6 unicast/multicast address family):
