y is shown in microseconds, but when you specify the delay in redistribution, you must use 10-microsecond units. That is, to achieve a delay of 100 microseconds, you would specify a delay value of 10. When I configure redistribution, I always make the reliability 255, loading 1, and MTU 1500. In fact, I usually make the redistributed routes appear as 100 Mbps links, as shown previously. Keep it simple. While there may be instances where you'll want to alter these values, those instances will be rare. The method of specifying a default metric, and overriding it with a specific metric described in "Redistributing into RIP," is also valid with EIGRP. Here, I've specified a default metric reflecting a 100 Mbps link with a delay of 100 microseconds, I'm redistributing OSPF process 100 with a metric reflecting a 1,000 Mbps links with a delay of 50 microseconds: router eigrp 100 redistribute ospf 100 metric 1000000 5 255 1 1500 Chapter 11: Redistribution network 10.0.0.0 default-metric 100000 10 255 1 1500 no auto-summary When redistributing OSPF routes into another protocol, you can limit the types of routes that are redistributed. For example, you can redistribute only OSPF internal routes, while ignoring all OSPF external routes. This is done by using the match key- word with the redistribute ospf command. R2 2(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: 2((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.
