B
The update will be ignored and no further action will occur Debug IP route
C
The updated information will replace the existing routing table entry
D
The existing routing table entry will be deleted from the routing table and all routers will exchange routing updates to reach convergence
Explanation: 

Detailed explanation-1: -Two connected routers are configured with RIP routing. What will be the result when a router receives a routing update that contains a higher-cost path to a network already in its routing table? The updated information will be added to the existing routing table.

Detailed explanation-2: -A router choses routing updates from difference routing protocols by the administrative distance of the routing protocol. The one with the lowest administrative distance will be chosen.

Detailed explanation-3: -Explanation: Both RIPv1 and RIPv2 support a maximum hop count of 15 because they use 4-bits to store this value. RIPv1 uses classful routing whereas RIPv2 uses classless routing. The routing updates are broadcasted over the network. It notifies routers about the update so that they update their own routing tables.
