The maximum metric is 15 because RIP was designed for small networks.
2:
Why doesn't RIP support discontiguous networks?
A2:
RIP is a classful protocol, so it summarizes the update at the major network boundary.
3:
Why doesn't RIP support VLSM?
A3:
When RIP sends the update, it checks to see whether the network being adver-tised has the same mask. If the advertised network has a different mask, RIP doesn't advertise that network.
4:
What is the default update interval for RIP?
A4:
The entire routing table is updated every 30 seconds.
5:
What transport protocol and port number do RIP use for sending updates?
A5:
RIP uses UDP port 520 to transport its update packets.
6:
What is the purpose of the split-horizon technique?
A6:
Split horizon is used in RIP to avoid routing loops .
7:
Does RIP Version 2 solve the discontiguous network problem by default?
A7:
No, the command no auto-summary is needed under router rip.
8:
Does RIP Version 2 also use broadcast for sending updates?
A8:
No, RIP Version 2 uses a multicast address of 224.0.0.9 to send its routing updates.
9:
Does RIP support authentication?
A9:
RIP Version 1 does not support authentication, but RIP Version 2 does support it.
