| 1: | What is the maximum metric in RIP? |
| A1: | 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. |
