Configuring basic MBGP functions

Before you configure MBGP, be sure that neighboring nodes can access each other at the network layer.
To configure basic MBGP functions:
Step
1. Enter system view.
2. Enter BGP view.
3. Specify a peer or peer group
and its AS number.
4. Enter IPv4 MBGP address
family view.
5. Enable a peer or peer group
created in IPv4 unicast view.
6. Specify a preferred value for
routes from an IPv4 MBGP
peer or peer group.

Controlling route advertisement and reception

Before configuring this task, configure basic MBGP functions first.

Configuring MBGP route redistribution

MBGP can advertise routing information in the local AS to neighboring ASs. It redistributes such routing
information from IGP into its routing table rather than learning the information by itself.
To configure MBGP route redistribution:
Configuring MBGP route preferences
Configuring the default local preference
Configuring the MED attribute
Configuring the NEXT_HOP attribute
Configuring the AS_PATH attributes
Configuring MBGP soft reset
Enabling the MBGP ORF capability
Configuring the maximum number of MBGP routes for load
balancing
Configuring IPv4 MBGP peer groups
Configuring MBGP community
Configuring an MBGP route reflector
