Question 1


The default timers of RIP and RIPng are the same. The meanings of these timers are described below:

Update: how often the router sends update. Default update timer is 30 seconds
Invalid (also called Expire): how much time must expire before a route becomes invalid since seeing a valid update; and place the route into holddown. Default invalid timer is 180 seconds
Holddown: if RIP receives an update with a hop count (metric) higher than the hop count recording in the routing table, RIP does not “believe in” that update. Default holddown timer is 180 seconds
Flush: how much time since the last valid update, until RIP deletes that route in its routing table. Default Flush timer is 240 seconds


Question 2

Question 3

Question 4

Question 5

Question 6


This is how to disable split horizon processing for the IPv6 RIP routing process named digitaltut:

Router(config)# ipv6 router rip digitaltut
Router(config-rtr)#no split-horizon

Note: For RIP (IPv4), we have to disable/enable split horizon in interface mode. For example: Router(config-if)# ip split-horizon

Reference: https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipv6/command/ipv6-cr-book/ipv6-s6.html

Question 7


This is how to change the timers for RIPng:

R1(config)#ipv6 router rip digitaltut
R1(config-rtr)#timers 5 15 10 30 (5: Update period; 15: Route timeout period; 10: Route holddown period; 30: Route garbage collection period)

Note: For IPv4 RIP, we have to change the timers in “(config-router)#”.

    RIPng is a UDP-based protocol. Each router that uses RIPng has a
    routing process that sends and receives datagrams on UDP port number
    521, the RIPng port

    So the stated answer is the correct one, C. I guess you have no clue what you’re talking about when you say that “most of the question are wrong”…study my friend.
