Super networking and EIGRP Failure

When super neting 2 class c address on a 2500 ethernet port

The EIGRP refuses to annouce the route to any EIGRP neighbors.

The EIGRP AS numbers are correct

No auto sum is being used at both ends

the Network statement is correct for the supernet

IP classless is configed on all routers

Problem has been duplicated in my lab using different verison of IOS

Have even tried using "IP summary eigrp" statement on the outgoing

interface.

Using debug the router will adversite all other networks but NEVER the

supernet

Has anybody ever done this before ? I can find no doucmention from cisco

that says yea or nay to this configration.

Re: Super networking and EIGRP Failure

Could you post your configs? I'd like to try it in our lab.

What was the answer to the routing question?

Re: Super networking and EIGRP Failure

Network statements for eigrp default to major network boundaries. You need to use the network statement with explicit mask that was introduced in 12.0(4)T so your config line would be "network 202.202.42.0 255.255.254.0"

Good luck and have fun!

Re: Super networking and EIGRP Failure

Sorry. Made a mistake in my reply - overlooked the mask used.

Vincent is right on.
