 an example, I have configured this router to redistribute OSPF routes from process 100 into EIGRP 100, but to include only internal routes and external type-2 routes: R2 (config-router)# redistribute ospf 100 match internal external 2 Because I have not specified a metric, the default metric will be used. I could have added a metric to the specific redistribution as well. Redistributing RIP into EIGRP is done the same way as redistributing OSPF, but there is no option for matching route types because RIP does not support the many types of routes that OSPF does: router eigrp 100 redistribute rip metric 100000 100 255 1 1500 Redistributing into OSPF Redistribution into OSPF is done in the same way as in the other protocols. The met- ric for an OSPF route is a derivative of the bandwidths of the links contained in the route. Setting the default metric in OSPF to 10 Mbps is done as follows: R3 (config-router)# default-metric 10 Redistributing into OSPF There are no other options. The metric can have a value of 1-16,777,214, with 1 being 100 Mbps (assuming default settings). If you do not specify a default metric or a metric on the redistribute command line, OSPF will assign a metric of 20 to all redistributed routes, except those from BGP, which will be assigned a metric of 1. While all redistributed routes are external, OSPF supports two types of external routes, which are cleverly described as type-1 and type-2 external routes. Type-1 routes are designated with 0 E1 in the routing table, while type-2 routes are desig- nated with 0 E2. E1 routes include the metric as set at the point of redistribution, plus the metric of all the links within the OSPF autonomous system. E2 routes only include the metric set at the point of redistribution. Figure 11-4 illustrates how the OSPF metrics change throughout a simple network depending on the external route type in use. 50.50.50.0/24 OSPF cost :10 OSPF cost :10 Redistribute connected If E1 route then metric=110 If E1 route then metric=120 with a metric of 100 If E2 route the
