    Study Notes

    Route Filtering

    • Route filtering gives network administrators tight control over route advertisements. Filters specify what routes are redistributed between protocols. This is important for security and to control the size of routing tables.

    Route Redistribution

    • Route redistribution occurs when a routing protocol advertises routes learned from other protocols, static routes, or direct connections.

    • This is useful for consolidating multiple routing domains in a network.

    • But, conflicts in routing metrics and administrative distances can lead to inaccurate routing, loops, or black holes when multiple routing protocols are used.

    Administrative Distances

    • Administrative distance is a metric associated with a route, representing its believability. Lower administrative distance routes are preferred over higher ones.

    • This helps determine which route to use when there are multiple routes to the same destination.

    • Different routing protocols have different administrative distances, such as RIP (120) and EIGRP (90). An administrator can configure custom administrative distances to influence route selection.

    Route Maps

    • Route maps are similar to access lists, but more flexible. They can match route attributes (like source or destination). They can also change route attributes.

    • They're commonly used for policy-based routing or redistribution.
