C HAPTER 51 | IP Routing Commands
Border Gateway Protocol (BGPv4)
– 1876 –
COMMAND USAGE
◆ 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.
◆ 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
◆ Route reflection from this device is enabled by default, but is only
functional if a client has been configured with this command.
◆ 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)#
