OmniSwitch 7700/7800/8800 Advanced Routing Configuration Guide

The following steps and points summarize configuring BGP. Not all of the following are necessary. For 
the necessary steps to enable BGP on the OmniSwitch, see 

.

1 Load the BGP protocol. See 

2 Set up router-wide parameters, such as the router’s AS number, default local preference, and enable the 
BGP protocol. See 

.

3 Configure peers on the router. These peers may be in the same AS as the router or in a different AS. 
See 

4 Configure peers that operate on remote routers. These peers may be in the same AS as the router or in a 
different AS. See 

.

5 Configure optional parameters. There are many optional features available in the Alcatel implementa-
tion of BGP-4. These features are described in later sections of this chapter. The following is a list of BGP 
features you can configure on the OmniSwitch 7700/7800/8800:

• Aggregate Routes. See 

• Local networks, or routes. See 

• Route Dampening. See 

• Route Reflection. See 

.

• Communities. See 

.

• Confederations. See 

• Route filtering based on AS path list, community affiliation, prefix list, or route map. 

• Redistribution of routes from another protocol, such as RIP or OSPF. See
