Step-by-Step Instructions:
1. Cable the lab as shown.
2. Complete the basic router setup on each router.
3. Configure the interfaces on each router.
4. Configure the routing protocol and advertise/associate/publish the router’s
networks.
5. If you have enough routers then test the maximum hop count by adding in enough
routers…I would suggest a total of 17. Ping from end to end and from the middle
out. Test that 16 hop count limit to the max! Otherwise skip this step.
6. Change the rip timer using these commands. Notice how I show you what the
previous (default) RIP timers are before I changed them. The format is updatesinvalid
timer-hold down timer-flush timer. Then I show you what they were after
I changed them:
Before (30-180-180-240):
scorpion#sh ip protocols
Routing Protocol is "rip"
Sending updates every 30 seconds, next due in 1 seconds
Invalid after 180 seconds, hold down 180, flushed after 240
Outgoing update filter list for all interfaces is
Incoming update filter list for all interfaces is
Redistributing: rip
Default version control: send version 1, receive any version
