switch(config-router-neighbor-af)#
route-reflector-client
Step 10

Example:
switch(config-router-neighbor-af)#
show bgp ip unicast neighbors
Step 11
copy running-config startup-config
Example:
switch(config-router-neighbor-af)#
copy running-config startup-config
This example shows how to configure the router as a route reflector and add one neighbor as a client:
switch(config)# router bgp 65536
switch(config-router)# neighbor 192.0.2.10 remote-as 65536
switch(config-router-neighbor)# address-family ip unicast
switch(config-router-neighbor-af)# route-reflector-client
switch(config-router-neighbor-af)# copy running-config startup-config

Configuring Route Dampening

You can configure route dampening to minimize route flaps propagating through your iBGP network.
To configure route dampening, use the following command in address-family or VRF address family
configuration mode:
Command
dampening [{ half-life reuse-limit
suppress-limit max-suppress-time |
route-map map-name }]
Example:
switch(config-router-af)# dampening
route-map bgpDamp

Chapter 11
Purpose
Configures the device as a BGP route reflector and
configures the neighbor as its client. This command
triggers an automatic notification and session reset for
the BGP neighbor sessions.
(Optional) Displays the BGP peers.
(Optional) Saves this configuration change.
Purpose
Disables capabilities negotiation. The parameter
values are as follows:
half-life—The range is from 1 to 45.
•
reuse-limit—The range is from 1 to 20000.
•
suppress-limit—The range is from 1 to 20000.
•
max-suppress-time—The range is from 1 to
•
255.
