Wildcard or summary route

poker911 · September 14

Hi

I'm self learning on CCNA, I've coma across a question that's confused me.

Eigrp has been enabled on R3, routing for networks 10.0.0.0/24

But R3 interfaces are 10.1.1.2 and 10.1.0.1....interfaces do not fall in the range of 10.0.0.0/24.

So you change it .....(config) no network 10.0.0.0 0.0.0.255

I'm confused as how you got 0.0.0.255??

Shouldn't that be 0.0.255.255? As a wild card mask?

Please can someone explain

Kind regards

Fun FACT:

Most people don't run EIGRP.

That's something you won't read in your Cisco Press books.

Focus on OSPF (and BGP later down the line)

it Sounds like the wildcard maks should really be: 0.255.255.255

which translates into a Subnet mask of: 255.0.0.0

So i suppose better possible answers to that question:

no network 10.0.0.0 0.255.255.255

or

no network 10.1.0.0 0.0.255.255
