BGP Route Reflector
For BGP routes in the same AS, an adjacency should be set up
between any two routers. Thus, with the increase of IBPG
routers, the number of neighbors will increase by n*(n-1)/2 (n
stands for the number of IBGP routers). To reduce the workload
of maintenance and configuration, route reflector and route
confederation are used.
For routers running IBGP in an AS, one router is selected as a
Router Reflector (RR), and all other IBGP routers serve as clients
only with adjacency set up with the RR. All clients reflect routes
through the RR. In this way, the number of neighbors is reduced
to n-1.
Refer to below procedure for BGP route reflector configuration
on ZTE ZXR10 GER.
„
Router Command Line Interface has been accessed.
„
BGP is running on a network.
1. For configuring BGP route reflector, use neighbor < ip-
address > route-reflector-client command in BGP route
mode as shown in Table 297.

This configures neighbors
as client peers of the route
reflector
Result: This configures neighbors as client peers of the route
reflector.
As shown in
Figure 102, there are two route reflectors in
AS100: R3 and R4. Where, the clients of R4 are R5 and R6,
while those of R3 are R1 and R2.
