Route Redistribution

Route redistribution is the interaction of multiple routing protocols. OSPF and RIP can be operated concurrently in the P330. In this case, the P330 can be configured to redistribute routes learned from one protocol into the domain of the other routing protocol. Similarly, static routes may be redistributed to RIP and to OSPF. Route redistribution involves metric changes and sometimes causes routing loops in the presence of other routes with incompatible schemes for route redistribution and route preferences. Be careful!

The the P330 scheme for metric translation in route redistribution is as follows:

•Static to RIP metric configurable (default 1)

•OSPF internal metric N to RIP metric 1

•OSPF external type 1 metric N to RIP metric 1

•OSPF external type 2 metric N to RIP metric N+1

•Static to OSPF external type 2, metric configurable (default 1)

•RIP metric N to OSPF external type 2, metric N

•Direct to OSPF external type 2, metric 1.

By default, the P330 does not redistribute routes between OSPF and RIP. Redistribution from one protocol to the other can be configured. By default, static routes are not redistributed to RIP and OSPF. The P330 allows the user to globally enable redistribution of static routes to RIP, and separately, to globally enable redistribution of static routes to OSPF. In addition, the P330 lets the user configure, on a per static route basis, whether the route is to be redistributed to RIP and OSPF, and what metric (in the range of 1-15). The default state is to enable the route to be redistributed at metric 1. When static routes are redistributed to OSPF, they are always redistributed as external type 2.
