Route redistribution
Route redistribution is the interaction of multiple routing protocols. OSPF and RIP can be
operated concurrently in the Branch Gateway. In this case, you can configure the Branch
Gateway to redistribute routes learned from one protocol into the domain of the other routing
protocol. Similarly, static routes can be redistributed to RIP and OSPF.
Note:
Take care when you configure route redistribution. It involves metric changes and might
cause routing loops in the presence of other routes with incompatible schemes for route
redistribution and route preferences.
The Branch Gateway scheme for metric translation in route redistribution is as follows:
• Static to RIP metric configurable (default 1)
• OSPF internal metric N to RIP metric (default 1)
• OSPF external type 1 metric N to RIP metric (default 1)
• OSPF external type 2 metric N to RIP metric (default 1)
• Static to OSPF external type 2, metric configurable (default 20)
