♦ RIP version 1
♦ RIP version 1 features
- Distance Vector Routing Protocol
- Route decision metric value is used by hop count
- hop count The maximum value is 15
- Broadcast the entire routing table to the neighboring router every 30 seconds.
- Load balance is basically 4 paths and can be up to 6
♦ RIP 1 periodic update
- 30 seconds for RIP, 90 seconds for IGRP
- If the cycle is short, the link congestion, and if the cycle is long, the propagation speed of the network change becomes slow.
♦ RIP 1 Broadcast Update
- When a router first connects to the network, it uses its broadcast address to notify itself of its information.
♦ Full update of the RIP 1 routing table
- Sends the contents of its routing table to neighboring routers
- Neighboring routers only record the necessary information and discard the rest.
♦ Routing loop
- Looping occurs because information on poor networks is not propagated quickly.
- There is a trigglered update method that updates without waiting for periodic update time for the changed network as a solution.
♦ RIP version 2
♦ RIP version 2 features
- hop count up to 15
- Over 15 values can not be processed due to looping occurrence.
- Limited use on large networks
♦ Hold down timer
- If the network is notified that the network is down, the router will start the hold down timer
- During the hold down timer operation, ignore the routing path information from the outside.
- hold down timer If the metric of the new path to the end or the destination is equal to or better than the existing metric
♦ Triggered Update
- hold down
- Do not wait until the routing table is updated after a line failure,
- Set to 'ip rip triggered'

- Do not send the same information to the place where the routing information comes in.
