Bgp Cluster-Id; Bgp Default Local-Preference - NETGEAR M6100 Series Reference Manual

bgp cluster-id

Use the bgp cluster-id command in BGP router configuration mode to specify the
cluster ID of a route reflector. To revert the cluster ID to its default, use the no form of this
command.
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.
Default A route reflector with an unconfigured cluster ID uses its BGP router ID (configured with
the cluster ID.

Format
no bgp cluster-id
Mode BGP Router Config

bgp default local-preference

Use this command 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 preference value is preferred.
BGP assigns the default local preference to each path received from an external peer. (BGP
retains the LOCAL_PREF on paths received from internal peers.) BGP also assigns the
default local preference to locally-originated paths. If you change the default local preference,
BGP automatically initiates a soft inbound reset for all peers to apply the new local
preference.
Default If this command is not given, BGP advertises a local preference of 100 in Update messages to internal
peers.
