Command Usage
â—† First, use route-map command to create a route map, and the match and set
commands to configure the route attributes to act upon. Then use this
command to specify neighbors to which the route map is applied.
â—† If the specified route map does not exist, all input/output route updates will be
filtered.
Example
Console(config-router)#neighbor 10.1.1.64 route-map RD in
Console(config-router)#
neighbor route-
reflector-client
This command configures this router as a route reflector and the specified neighbor
as its client. Use the no form to disable route reflection for the specified neighbor.
Syntax
[no] neighbor {ip-address | group-name} route-reflector-client
ip-address – IP address of a neighbor.
group-name – A BGP peer group containing a list of neighboring routers
configured with the neighbor peer-group command.
Command Mode
Router Configuration
Default Setting
Disabled
Command Usage
â—† Route reflection from this device is enabled by default, but is only functional if a
client has been configured with this command.
â—† Under standard configuration rules, all BGP speakers within the same AS must
be fully meshed. Route reflection can used to reduce the number of
connections required between peers. Reflector clients exchange messages only
with the route reflector, while the reflector handles message exchanges among
each client and other iBGP, eBGP, and non-client routers. For more information
on configuring route reflection, refer to the Command Usage section under the
bgp client-to-client reflection command.
Example
Console(config-router)#neighbor 10.1.1.64 route-reflector-client
Console(config-router)#
