Configuring Bgp Load Balancing; Forbidding Session Establishment With A Peer Or Peer Group; Configuring A Large Scale Bgp Network; Configuration Prerequisites - HP MSR2000 series Configuration Manual

Configuring BGP load balancing

If multiple paths to a destination exist, you can configure load balancing over such paths to improve link
utilization.
To configure BGP load balancing:
Step
1. Enter system view.
2. Enter BGP view.
3. Configure the maximum number of
BGP routes for load balancing.

Forbidding session establishment with a peer or peer group

Step
1. Enter system view.
2. Enter BGP view.
Forbid session establishment with a
3.
peer or peer group.

Configuring a large scale BGP network

In a large-scale BGP network, configuration and maintenance become difficult because of the large
numbers of BGP peers. To facilitate configuration, you can configure peer group, community, route
reflector, or confederation as needed.

Configuration prerequisites

Peering nodes are accessible to each other at the network layer.

Configuring BGP peer groups

A peer group is a group of peers with the same route selection policy.
In a large-scale network, many peers may use the same route selection policy. You can configure a peer
group and add these peers into this group. In this way, peers can share the same policy as the peer
group. When the policy of the group is modified, the modification also applies to peers in it, simplifying
configuration.
A peer group is an IBGP peer group if peers in it belong to the same AS, and is an EBGP peer group if
peers in it belong to different ASs.
If a peer group has peers added, you cannot remove its AS number using the undo form of the command
or change its AS number.
