•
Flash memory conservation – Using peer groups instead of individually configuring all the parameters for
each neighbor requires fewer configuration commands in the startup-config file.
You can perform the following tasks on a peer-group basis.
•
Reset neighbor sessions
•
Perform soft-outbound resets (the Layer 3 Switch updates outgoing route information to neighbors but does
not entirely reset the sessions with those neighbors)
•
Clear BGP message statistics
•
Clear error buffers
Peer Group Parameters
You can set all neighbor parameters in a peer group. When you add a neighbor to the peer group, the neighbor
receives all the parameter settings you set in the group, except parameter values you have explicitly configured
for the neighbor. If you do not set a neighbor parameter in the peer group and the parameter also is not set for the
individual neighbor, the neighbor uses the default value.
You can set the following neighbor parameters using a peer group:
•
Advertisement interval
•
Default-information-originate
•
Description
•
Distribute list
•
EBGP multihop
•
Filter list
•
Maximum prefix
•
Next-hop-self
•
Password
•
Prefix-list
•
Remote AS
•
Remove private AS
•
Route map
•
Route reflector client
•
Send community
•
Shutdown
•
Timers
•
Update source
•
Weight
Configuration Rules
The following rules apply to peer group configuration:
•
You must configure a peer group before you can add neighbors to the peer group.
•
If you remove a parameter from a peer group, the value for that parameter is reset to the default for all the
neighbors within the peer group, unless you have explicitly set that parameter on individual neighbors. In this
case, the value you set on the individual neighbors applies to those neighbors, while the default value applies
to neighbors for which you have not explicitly set the value.
