13-30 config bgp route_reflector cluster_id
Description
This command is used to configure the BGP process's global attribute. The route reflector and its
clients together form a cluster. When a single route reflector is deployed in a cluster, the cluster is
identified by the router ID of the route reflector.
When the cluster ID is 0.0.0.0, the cluster is identified by the router ID. Otherwise, the cluster is
identified by the cluster ID.
The BGP cluster_id command is used to assign a cluster ID to a route reflector when the cluster
has one or more route reflectors. Multiple route reflectors are deployed in a cluster to increase
redundancy and to avoid a single point of failure. When multiple route reflectors are configured in a
cluster, they must be configured with the same cluster ID. This allows all route reflectors in the
cluster to recognize updates from peers in the same cluster and reduces the number of updates
that needs to be stored in BGP routing tables.
This command is only required for the reflector and not the client.
Format
config bgp route_reflector cluster_id <ipaddr>
Parameters
cluster_id - Specifies the IP address of the cluster ID. Setting the cluster ID to 0.0.0.0 will
remove specifications of the cluster ID. The default value is 0.0.0.0.
<ipaddr> - Enter the cluster ID's IP address here.
Restrictions
Only Administrator, Operator and Power-User level users can issue this command. (EI Mode Only
Command)
Example
This example shows how to configure the cluster ID:
DGS-3620-28SC:admin#
Command: config bgp route_reflector cluster_id 10.100.200.1
Success.
DGS-3620-28SC:admin#
