Optional) Disabling Route Reflection Between Clients - Huawei S6700 Series Configuration Manual

S6700 Series Ethernet Switches
Configuration Guide - IP Routing
After receiving IBGP routes, the RR selects optimal routes based on BGP route selection policies
and advertises learned routes to its clients and non-clients following the rules described below:
l

In addition, the RR advertises learned EBGP routes to all non-clients and clients.
It is easy to configure an RR. The RR functionality only needs to be configured on one switch.
Configurations on clients are not required.
Perform the following steps on the switch that is running BGP and is to be specified as an RR:
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
ipv4-family unicast
The IPv4 unicast address family view is displayed.
Step 4 Run:
peer { ipv4-address | group-name } reflect-client
The switch is specified as an RR and its clients are configured.
To add more clients, repeat the step.
reflect-client configured in an address family is valid only in this address family and cannot be
inherited by other address families. Configuring reflect-client in a specified address family is
recommended.

7.9.3 (Optional) Disabling Route Reflection Between Clients

If the clients of an RR are fully meshed, prohibiting route reflection among the clients can reduce
the link cost.
Context
The RR usually advertises the routes learned from clients to all non-clients and clients. If full-
mesh logical connections have been established between all the clients of the RR, the clients are
capable of sending routes to each other without the help of the RR. Route reflection can be
disabled between clients to reduce the stress on the RR.
Perform the following steps on the RR that is running BGP.
