Injecting OSPF Routes into the BGP Routing Table

You can specify a match condition for policies based on procotols by naming a
protocol from which the route is learned or to which the route is being advertised.
You can specify one of the following protocols: aggregate, BGP, direct, DVMRP,
IS-IS, local, OSPF, PIM-dense, PIM-sparse, RIP, or static
For example, you can inject or redistribute OSPF routes into the BGP
routing table by creating a routing policy.
