H3C S5600 Series Ethernet Switches
Activate a specified BGP
peer
Enable BGP logging
Specify the source
interface for route update
packets
Allow routers that belong
to non-directly connected
networks to establish
EBGP connections.
Note:
To configure basic functions of BGP peer group, you need to create the BGP peer
group first. Refer to section
about creating a BGP peer group.
In order for route updating packets being sent even if problems occur on interfaces,
you can configure the source interfaces of route update packets as a loopback
interface.
Normally, EBGP peers are connected through directly connected physical links. If
no such link exists, you need to use the peer ebgp-max-hop command to allow
the peers to establish multiple-hop TCP connections between them. If loopback
interfaces are used to establish connections between EBGP peers, the peer
ebgp-max-hop command is unnecessary.
Note the following:
It is required to specify for a BGP router a router ID, a 32-bit unsigned integer and
the unique identifier of the router in the AS.
To do... Use the command...
peer { group-name |
ip-address } enable
log-peer-change
peer { group-name |
ip-address }
connect-interface
interface-type
interface-number
peer group-name
ebgp-max-hop
[ hop-count ]
5.7.2 "Configuring BGP Peer
Optional
By default, a BGP peer is
active.
Optional
By default, BGP logging is
enabled.
Optional
By default, the source
interface of the optimal route
update packets is used as the
source interface.
Optional
By default, routers that belong
to two non-directly connected
networks cannot establish
EBGP connections.
You can configure the
maximum hops of EBGP
connection by specifying the
hop-count argument.
