As shown the network topology, all routers are used distance vector routing algorithm to calculate the route two subnets (Note: a route metric using subnet number of hops). 
If the route table structure shown in the following table.
| The purpose network |
interface |
please answer the following question:
(1) If all routers have converged, please give R1 routing table, routes to all subnets requirements include the drawings, and the routing entry in the routing table as small as possible.
(2) In all routers have converged state, suddenly detected subnet 192.168.1.128/26 R3 unreachable, R2 and R3 are simultaneously if the following distance vector to exchange R1, R1 of the updated routing table that? What R1 after the update is a distance vector?
