BGP Configuration Commands
6-88 Configuring the Border Gateway Protocol
Example
This example first disables the default reflection setting on this router then restores the default:
XSR(config)#router bgp 100
XSR(config-router)#no bgp client-to-client reflection
XSR(config-router)#bgp client-to-client reflection
bgp cluster-id
This command sets the cluster identifier for a BGP cluster that contains more than one route
reflector. A cluster is comprised of one or more route reflectors and clients of those reflectors.
Clusters containing one route reflector are identified by the router identifier of the route reflector.
Syntax
bgp cluster-id cluster-id
Syntax of the “no” Form
The no form of this command resets the cluster identifier to the default:
no bgp cluster-id
Mode
Router configuration: XSR(config-router)#
Default
The default value is the router identifier of the route reflector in the cluster.
Example
The following example configures the bgp cluster‐id value within the BGP process 600. The BGP
process corresponds to the AS in which the router resides. The cluster ID is configured as 88. This
example configures the cluster ID with two route reflector clients (192.168.1.1, 192.168.1.2).
XSR(config)#router bgp 600
XSR(config-router)#bgp cluster-id 88
XSR(config-router)#neighbor 192.168.1.1 remote-as 600
XSR(config-router)#neighbor 192.168.1.1 route-reflector-client
XSR(config-router)#neighbor 192.168.1.2 remote-as 600
XSR(config-router)#neighbor 192.168.1.2 route-reflector-client
bgp confederation identifier
This command sets a BGP confederation identifier for a confederation of ASs. A confederation
identifier is a valid AS number that represents a confederation comprised of two or more ASs. A
confederation appears as a single AS to ASs outside of the confederation.
cluster-id The cluster of the XSR acting as a route reflector. Valid values are cluster
identifiers of up to 4 bytes. Range: 1 to 4294967295 or A.B.C.D (IP address
format).
