• cluster-id-A non-zero 32-bit identifier that uniquely identifies a cluster of route reflectors and their clients. The cluster ID may be entered in dotted notation like an IPv4 address or as an integer. Default Configuration A route reflector whose cluster ID has not been configured uses its BGP router ID (configured with bgp router-id) as the cluster ID. Command Mode BGP Router Configuration mode, BGP Router VRF Configuration User Guidelines A route reflector and its clients form a cluster. Since a cluster with a single route reflector has a single point of failure, a cluster may be configured with multiple route reflectors. To avoid sending multiple copies of a route to a client, each route reflector in a cluster should be configured with the same cluster ID. Route reflectors with the same cluster ID must have the same set of clients; otherwise, some routes may not be reflected to some clients. The same cluster ID is used for both IPv4 and IPv6 route reflection. Command History Introduced in version 6.2.0.1 firmware. Command mode updated in version 6.8 firmware. Example console(config-router)#bgp cluster-id 1 bgp default local-preference Use the bgp default local-preference command to enable the network operator to specify the default local preference. Local preference is an attribute sent to internal peers to indicate the degree of preference for a route. A route with a numerically higher local value is preferred over a route with a numerically lower value. Syntax bgp default local-preference number Layer 3 Routing Commands 1319
