Use of EIGRP Passive Interface Command

[charliefiroozabadi]

Hello,

I'm configuring a 2900 router with one Gigabit LAN interface (GI 0/0) that I've broken to multiple subinterfaces as I have 5 diffrent subnets/VLANs.  If I want supress EIGRP advertisments to any of those subnets, should I disable it at physical interface level) or for each individual subinterface?

Thank you,

Easiest way would be to use "passive-interface default" then "no passive-interface " on the one you want to forward updates from.

However if you do not want to do that, it would be "passive-interface " for each of the sub interfaces.

Gregory,

Thank you for your prompt reply.  I'll use "passive interface default" tehnique.

Have a good day!
