Operating a Network Using Multiple IP Routing Protocols参考.ppt

Manipulating Routing Updates Operating a Network Using Multiple IP Routing Protocols Using Multiple IP Routing Protocols Using Multiple Routing Protocols Interim during conversion Application-specific protocols One size does not always fit all. Political boundaries Groups that do not work well with others Mismatch between devices Multivendor interoperability Host-based routers Redistributing Route Information Using Seed Metrics Use the default-metric command to establish the seed metric for the route or specify the metric when redistributing. Once a compatible metric is established, the metric will increase in increments just like any other route. Redistribution with Seed Metric Summary Using multiple IP routing protocols can be a result of migrating to a more advanced routing protocol, a multivendor environment, political boundaries, or device mismatch. The way that redistributed routes will appear in the routing table will vary depending on the protocols being redistributed and how they are redistributed. The seed metric is the metric associated with the redistributed route and should make the route appear worse than any internal route. Manipulating Routing Updates Configuring and Verifying Route Redistribution Redistribution Supports All Protocols Configuring Redistribution into RIP Redistributing into RIP Configuring Redistribution into OSPF Default metric is 20. Default metric type is 2. Subnets do not redistribute by default.
