client-to-client
Enables route reflection between clients in a cluster.
Syntax
client-to-client {reflection}
Parameters reflection — Enter to enable reflection of routes allowed in a cluster.
Default Enabled
Command Mode ROUTER-BGP
Usage
Information
Configure the route reflector to enable route reflection between all clients. You must fully mesh all clients
before you disable route reflection. The no version of this command disables route reflection in a cluster.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
2. From the ROUTER BGP mode, enter the ROUTER BGP VRF mode using the vrf vrf-name
command.
Example
OS10(conf-router-bgp-2)# client-to-client reflection
Supported
Releases
10.2.0E or later
cluster-id
Assigns a cluster ID to a BGP cluster with multiple route reflectors.
Syntax
cluster-id {number | ip-address}
Parameters
● number—Enter a route reflector cluster ID as a 32-bit number, from 1 to 4294967295.
● ip-address—Enter an IP address as the route-reflector cluster ID.
Default Router ID
Command Mode ROUTER-BGP
Usage
Information
If a cluster contains only one route reflector, the cluster ID is the route reflector’s router ID. For
redundancy, a BGP cluster may contain two or more route reflectors. Without a cluster ID, the route
reflector cannot recognize route updates from the other route reflectors within the cluster. The default
format to display the cluster ID is A.B.C.D format. If you enter the cluster ID as an integer, an integer
displays. The no version of this command resets the value to the default.
NOTE: To configure these settings for a nondefault VRF instance, you must first enter the ROUTER-
CONFIG-VRF sub mode using the following commands:
1. Enter the ROUTER BGP mode using the router bgp as-number command.
