This is not a good idea to run two different protocols in a router unless you have criteria. For example, the router is going to perform redistribution.

[7:23298] Admin Distance comes into play when both routing protocols have exactly the same route. For example route 10.1.1.0 mask 255.255.255.0 If both RIP2 and OSPF know about this exact route then the route from OSPF would be used. This is because OSPF has an admin distance of 110 versus RIP of 120. Lets take another example. Lets say OSPF knows about the route as part of a larger aggregate such as 10.1.0.0 mask 255.255.254.0 or a /23 mask. Lets also say the RIP2 still knows about the route as 10.1.1.0 mask 255.255.255.0 or /24bit. In this second case the RIP route would be chosen because it has a more exact match. In this case Administrative distance never came into play at all. Mike Paulson Network engineer. tuffgong wrote: > That is not the case.
