9.5 Configuring the Policy for Exchanging Routes Between
MBGP Peers
By configuring a proper route exchange policy, you can control the routing information
exchanged between MBGP peers.

9.5.1 Establishing the Configuration Task

Before configuring a policy for exchanging routes between MBGP peers, familiarize yourself
with the applicable environment, pre-configuration tasks, and required data. This can help you
complete the configuration task quickly and accurately.
Applicable Environment
Based on the actual network, users can configure the related route exchange polices to control
the routing information transmitted between MBGP peers.
For a switch configured with MBGP, the routes exchanged between peers are classified into the
following types:
