Disabling or re-enabling client-to-client route reflection
26
BigIron RX(config-bgp)# bgp-redistribute-internal
Syntax: [no] bgp-redistribute-internal
To disable redistribution of IBGP routes into RIP, ISIS, and OSPF, enter the following command.
BigIron RX(config-bgp)# no bgp-redistribute-internal
Disabling or re-enabling client-to-client route reflection
By default, the clients of a route reflector are not required to be fully meshed; the routes from a
client are reflected to other clients. However, if the clients are fully meshed, route reflection is not
required between clients.
If you need to disable route reflection between clients, enter the following command. When the
feature is disabled, route reflection does not occur between clients but reflection does still occur
between clients and non-clients.
BigIron RX(config-bgp)# no client-to-client-reflection
Enter the following command to re-enable the feature.
BigIron RX(config-bgp)# client-to-client-reflection
Syntax: [no] client-to-client-reflection
Configuring a route reflector
You can configure one cluster ID on the router. All route-reflector clients for the router are
members of the cluster.
To configure a device as route reflector 1, enter the following command.
BigIron RX(config-bgp)# cluster-id 1
Syntax: [no] cluster-id <num> | <ip-addr>
The <num> | <ip-addr> parameter specifies the cluster ID (1 – 4294967295) or an IP address.
The default is the router ID.
NOTE
If the cluster contains more than one route reflector, you need to configure the same cluster ID on
all the route reflectors in the cluster. The cluster ID helps route reflectors avoid loops within the
cluster.
Enabling or disabling comparison of the router IDs
Router ID comparison is step 11 in the algorithm BGP4 uses to select the next path for a route.
NOTE
Comparison of router IDs is applicable only when BGP4 load sharing is disabled.
When router ID comparison is enabled, the path comparison algorithm compares the router IDs of
the neighbors that sent the otherwise equal paths.
