networks in eigrp

carl_townshend · ‎04-10-2006

If I need to advertise my subnetted class c /26 networks on my router which are on 4 sub interfaces, do I just need to advertise the whole /24 of the subnetted address /

thanks

You can advertise all of them separately as /26 or summarize them as a /24. Configuring a network statement for the class C will automatically cause the router to advertise them as /26 routes.

If you want to summarize them, you will need to configure "ip summary-address eigrp" on the interfaces where you want summarization to take place.

Hope this helps,
