hat are redistributed. For example, you can redistribute only OSPF internal routes, while ignoring all OSPF external routes. You do SO by using the match keyword with the redistribute ospf command: (config-router)#redistribute ospf 100 match ? external Redistribute OSPF external routes internal Redistribute OSPF internal routes nssa-external Redistribute OSPF NSSA external routes When matching external routes, you can also differentiate between OSPF type-1 and type-2 routes: (config-router) #redistribute ospf 100 match external ? Redistribute external type 1 routes Redistribute external type 2 routes external Redistribute OSPF external routes internal Redistribute OSPF internal routes match Redistribution of OSPF routes metric Metric for redistributed routes nssa-external Redistribute OSPF NSSA external routes route-map Route map reference Finally, you can combine route types with the match keyword. As 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. You redistribute RIP into EIGRP in 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 You redistribution into OSPF in the same way as in the other protocols. The metric for an OSPF route is a derivative of the bandwidths of the links contained in the route. Set the default metric in OSPF to 10 Mbps as follows: R3 (config-router)#default-metric 10 There are no other options. The metric can have a value of 1-16,777,214, with 1 being 100 Mbps (assuming default settings). Chapter 11: Redistribution If you do not specify a default metric or a metric on the redistri
