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

EBGP session to an
indirectly-connected peer or

maximum hop count.

By default, BGP cannot establish
an EBGP session to an
indirectly-connected peer or peer
group.
