BLADEOS 6.5.2 Application Guide

Aggregating Routes

Aggregation is the process of combining several different routes in such a way that a single route can be advertised, which minimizes the size of the routing table. You can configure aggregate routes in BGP either by redistributing an aggregate route into BGP or by creating an aggregate entry in the BGP routing table.

To define an aggregate route in the BGP routing table, use the following commands:

>># router bgp

>>(config-router-bgp)#aggregate-address<1-16> <IPv4 address> <mask>

>>(config-router-bgp)#aggregate-address <1-16>enable

An example of creating a BGP aggregate route is shown in “Default Redistribution and Route Aggregation Example” on page 270.

Redistributing Routes

In addition to running multiple routing protocols simultaneously, BLADEOS software can redistribute information from one routing protocol to another. For example, you can instruct the switch to use BGP to re-advertise static routes. This applies to all of the IP-based routing protocols.

You can also conditionally control the redistribution of routes between routing domains by defining a method known as route maps between the two domains. For more information on route maps, see “What is a Route Map?” on page 261. Redistributing routes is another way of providing policy control over whether to export OSPF routes, fixed routes, and static routes. For an example configuration, see “Default Redistribution and Route Aggregation Example” on page 270.

Default routes can be configured using the following methods:

￿Import

￿Originate—The router sends a default route to peers if it does not have any default routes in its routing table.

￿Redistribute—Default routes are either configured through the default gateway or learned via other protocols and redistributed to peer routers. If the default routes are from the default gateway, enable the static routes because default routes from the default gateway are static routes. Similarly, if the routes are learned from another routing protocol, make sure you enable that protocol for redistribution.
