458CHAPTER 30: CONFIGURING BGP

By default, send no community attribute to any peer group.

6Configure a peer group as the client of a BGP reflector

In general, the AS requires that all the IBGP routers should be connected to one another, and the routes sent by the IBGP neighbors is not advertised, to prevent route loop. However, if the route reflector is used, not all IBGP speakers are required to be fully connected. This technique requires configuring an internal BGP peer as a router reflector. Other internal peers are not necessarily mesh connected but set up an IBGP session with the route reflector and learn routes through the route reflector. Using peer reflect-clientcommand, you can configure internal neighbors which can communicate with the route reflector. These neighbors are the client-group members of the route reflector. Other neighbors are the non-client-group members.

Generally, it is unnecessary to configure this command for the peer entity since the IBGP peer is in its default group. You should use the peer peer-addressreflect-clientcommand to configure the route reflector client.

7Configure to send the default route to the peer group

Table 534 Configure to Send the Default Route to the Peer Group

Operation	Command
Configure to send the default route to	peer group-name
peer group	default-route-advertise
Do not allow to send default route to the	undo peer group-name
peers	default-route-advertise

By default, the local router does not advertise the default route to any peer group.

A next hop should be sent to the peer unconditionally as the default route.

8Set the router’s own IP address as the next hop when the peer group distributes route information.

Cancel the processing of next hop when sending a route to the peer and take the self-address as the next hop.

Table 535 Set the Own IP address as Next Hop When Peer Group Distributes Route

Operation	Command
Set the own IP address as next hop when	peer group-namenext-hop-local
peer group distributes route
Not to set the own IP address as next hop	undo peer group-namenext-hop-local
when peer group distributes route

By default, the router’s own IP address is not set as the next hop when the peer group distributes routes.
