Identifying Static and Dynamic Routes

•Static RouteUses a route that a network administrator enters into the router manually

•Dynamic RouteUses a route that a network routing protocol adjusts automatically for topology or traffic changes

Page 2: 1 Identifying Static and Dynamic Routes Static Route Uses a route that a network administrator enters into the router manually Dynamic Route Uses a route

Default Route Example

• Routing protocols are used between routers to determine paths and maintain routing tables.

• Once the path is determined a router can route a routed protocol.

Autonomous System 100 Autonomous System 200

IGPs: RIP, IGRP EGPs: BGP

– An autonomous system is a collection of networks under a common administrative domain– IGPs operate within an autonomous system– EGPs connect different autonomous systems

• Routers set the distance to infinity if the destination is routed on that link

Hold-Down Timers

• Router keeps an entry for the network down state, allowing time for other routers to recompute for this topology change

Dynamic Routing Configuration

– Defines an IP routing protocol

Router(config)#router protocol [keyword]

• Mandatory configuration command for each

IP routing process

• Identifies the physically connected network that routing updates are forwarded to

Router(config-router)#network network-number

– Hop count metric selects the path– Routes update every 30 seconds
