Bgp Cluster-Id - Dell N1100-ON Reference Manual

Syntax
bgp client-to-client reflection
no bgp client-to-client reflection
Default Configuration
Client-to-client reflection is enabled by default when a router is configured as
a route reflector.
Command Mode
IPv6 Address Family Configuration mode
User Guidelines
Route reflection can change the routes clients select. A route reflector only
reflects those routes it selects as best routes. Best route selection can be
influenced by the IGP metric of the route to reach the BGP next hop. Since a
client's IGP distance to a given next hop may differ from route reflector's IGP
distance, a route reflector may not re-advertise a route a client would have
selected as best in the absence of route reflection. One way to avoid this
effect is to fully mesh the clients within a cluster. When clients are fully
meshed, there is no need for the cluster's route reflectors to reflect client
routes to other clients within the cluster. When client-to-client reflection is
disabled, a route reflector continues to reflect routes from non-clients to
clients and from clients to non-clients.
The same command is available in BGP Router Configuration mode for IPv4
routes.
Command History
Introduced in version 6.2.0.1 firmware.

console(config-router-af)#bgp client-to-client reflection
