For advanced control over BGP Weight attribute, Route Maps can be used. To recall, Weight attribute is used by BGP to break the tie when there are more routes to the same network. Route with the highest weight is preferred. Weight attribute is a Cisco feature, it has local meaning and it is not transmitted to other routers.

When BGP has multiple paths to the same destination it must decide which one to select. The route selection process is based on attributes, where the Weight attribute is the first one that BGP takes into account when deciding which path to choose in order to reach the destination.

Redistribution into EIGRP by using Route Maps is done similarly as with OSPF. In an earlier entry there is a lab for configuring redistribution into EIGRP without using Route Maps, here we’ll use the same topology in GNS3.

Earlier we discussed about how to redistribute routes into OSPF by using standard method. In this article we will use the same topology and will do redistribution into OSPF by using Route Maps.

Route Maps represent a powerful tool for manipulating ip routes and packets. Route maps are somewhat similar to Access Lists but are more complex and more powerful. This article describe the basics of route maps on Cisco devices, and what they are used for. Route maps are widely used by:
