Answer the following with reference to this diagram: Router 1 Eth0/0 10.1 Router 5 Big Ser 0/0 10.2 Router 2 Router 6 Eth0/0 10.5 Sm Ser 0/0 10.1...

Please see networking problem attached.  

a.  Build a routing table for Router 6 that supports the routing of datagrams to every IP address shown in the diagram using the minimum number of hops to the destination.  (Assume other routers have appropriately defined routing tables.)b.  Most likely in answer a. you have two route table entries (Router 6) for the routing of datagrams to the 10.0.20 subnet and 10.0.30 subnet.  Show how to use address summarizing to reduce these entries to one line in the routing table (for Router 6).
