A networking student is learning that (AD) Administrative Distance rates the reliability of routing information received from neighboring routers. When multiple routes to the same network and subnet masks are received, the router prioritizes the route with the lower AD. However, if there are two identical network addresses, and each with a different subnet mask and both networks are configured with RIP and OSPF, how is the route determined?
a)
Routers will always choose the ‘smallest’ network (longest subnet mask) that an IP address matches first as a result of the different subnet masks.
b)
The router will look for the lowest administrative distance if two routing protocols have identical subnet masks for a destination.
c)
Once a routing protocol is chosen, the route with the lowest metric (hop count/cost) will be chosen.
d)
The path will depend on either RIP or OSPF.
