ospf work with a time then its takes automatically eigrp

Answer / jj

HI guys just a little modification here.
yes of course it wiil work but the question which protocol
to be used for the packet transfer.is it eigrp or ospf.
theoretically all guys will reply eigrp based on ad valve
but in this case it will take ospf
surprise? i lknow
let me explain......
the ad valve work only if the mask is same means if i
configure the routing protocol eigrp and ospf on same router
for the network x.x.x.x/16 and y.y.y.y/16 then sure it will
take eigrp but if i configure the ospf for the subnet
x.x.x.x/24 and eigrp for y.y.y.y/16 it will take ospf
because it have higher sub-net mask.
