Question, I have 2 1700 routers connected to 2 switches on each end and computers on each end. When I network OSPF, ping from one computer end to the other works fine, when I try EIGRP or RIP it's not becoming adjacent, all my masks are Why is this happening ?

I have this problem too.

Hello Sergej,

you should provide more info to get better help.

I would suggest you to post a filtered version of the two routers configuration removing users and passwords and changing/masking the public ip addresses.

My guess is that RIP and EIGRP by default performs auto-summary at major network boundary for their distance vector nature while OSPF doesn't.

This can be a problem if you have two parts of the same major network divided by another one.

For example -- R1 --- --- R2 ---

try on rip / eigrp

router rip

version 2

no auto-summary

router eigrp xx

no auto-summary

Hope to help
