eigrp wildcard & no auto-summary

anccnadi

Can you use a wildcard instead of no auto-summary? Is it such that if you don't use a wildcard then you would need to use no auto-summary command? Help, I'm confused!

hi,

these both items dont affect each other

with the wildcard mask you define the networks (interfaces) which should participate in eigrp

the auto / no auto then works like an on/off button to determine if advertisments should be summerized inte classfull boundries

wildcards and auto-summary aren't really related. You use a wildcard to specify which interface runs EIGRP. No auto-summary is used to prevent EIGRP from summarizing routes back to the classful address.

Edit: meh, I was too late and ended up repeating what martell is saying
