This chapter from CCNP Routing and Switching Portable Command Guide provides information about redistribution topics.
This chapter is from the book

This chapter provides information about the following redistribution topics:

  • Defining seed and default metrics
  • Redistributing connected networks
  • Redistributing static routes
  • Redistributing subnets into OSPF
  • Assigning E1 or E2 routes in OSPF
  • Redistributing OSPF internal and external routes
  • Configuration example: route redistribution for IPv4
  • Configuration example: route redistribution for IPv6
  • Verifying route redistribution
  • Route filtering using the distribute-list command

    • Configuration example: inbound and outbound distribute list route filters
    • Configuration example: controlling redistribution with outbound distribute lists
    • Verifying route filters
  • Route filtering using prefix lists

    • Configuration example: using a distribute list that references a prefix list to control redistribution
    • Verifying prefix lists
  • Using route maps with route redistribution

    • Configuration example: route maps
  • Manipulating redistribution using route tagging
  • Changing administrative distance for internal and external routes
  • Passive interfaces

Defining Seed and Default Metrics

Router(config)#router eigrp 100

Starts the EIGRP routing process.


Specifies which network to advertise in EIGRP.

Router(config-router)#redistribute rip

Redistributes routes learned from RIP into EIGRP.

Router(config-router)#default-metric 1000 100 250 1 1500


The metrics assigned to these learned routes will be calculated using the following components:

Router(config-router)#redistribute rip metric 1000 100 250 1 1500

1000 = Bandwidth in Kbps

100 = Delay in tens of microseconds

255 = Reliability out of 255

1 = Load out of 255

1500 = Maximum transmission unit (MTU) size

The metric keyword in the second option assigns a starting EIGRP metric that is calculated using the following components: 1000, 100, 255, 1 1500.
