Layer 3 Routing Commands 1254
In BGP Router Configuration mode, this command only affects
advertisement of IPv4 routes. The same command is available in Address-
Family IPv6 Configuration mode for IPv6 routes.
Command History
Introduced in version 6.2.0.1 firmware.
Example
console(config-router)#bgp client-to-client reflection
bgp client-to-client reflection (IPv6 Address
Family Configuration)
Use the bgp client-to-client reflection command to enable client-to-client
reflection. By default, a route reflector reflects routes received from its clients
to its other clients. However, if a route reflector’s clients have a full iBGP
mesh, the route reflector does not reflect to the clients.
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
