what is used for passive intercae comand

mine answer-to prevent to take update from outside

Answer Posted / shahin

No dude... little bit different.

Passive interface command is used to control the
advertisement of routing information.

Most of the routing protocol, PASSIVE INTERFACE command
restrict outgoing advertisements only. But the case is
little bit different in EIGRP. In EIGRP, when PASSIVE
INTERFACE command is enable between two routers, it not only
suppressing routing updates but also HELLO MESSAGES also. In
result, router also lost the neighbor relationship with
router. So it also suppress the incoming updates also.

Hope it'll help u people. Let me know my feedback..!!!

Thanx dude for such a good question. Keep posting.
