44, the G8264CS is configured as a route reflector. All clients and

non‐clients are in the same AS.

Figure 44. iBGP Route Reflector

RR Non-Client

The following attributes are used by the route reflector functionality:

ORIGINATOR ID: BGP identifier (BGP router ID) of the route originator in the

local AS. If the route does not have the ORIGINATOR ID attribute (it has not

been reflected before), the router ID of the iBGP peer from which the route has

been received is copied into the Originator ID attribute.This attribute is never

modified by subsequent route reflectors. A router that identifies its own ID as

the ORIGINATOR ID, it ignores the route.

CLUSTER LIST: Sequence of the CLUSTER ID (the router ID) values

representing the reflection path that the route has passed. The value configured

with the cluster-id command (or the router ID of the route reflector if the

cluster-id is not configured) is prepended to the Cluster list attribute. If a

route reflector detects its own CLUSTER ID in the CLUSTER LIST, it ignores the

route. Up to 10 CLUSTER IDs can be added to a CLUSTER LIST.
