if I wanted to advertise routes across vlans from the core router,say they are 4 subinterfaces, each on a different subnet, 172.19, 172.20, 172.21, 172.22, on the eigrp network statement would i just put network 188.8.131.52 0.255.255.255 and use the no-auto summarary command, would this advertise each individual routes to the neighbours, or would I need to add each individual network ?
Yes, that would accomplish what you want - each network will be advertised individually.
However, the problem with using a network statement that covers a range such as the above is that you may inadvertently enable EIGRP on any future links that have other IP addresses in the 172.x.x.x range. If you list them explicitly, you know precisely which interfaces EIGRP will be enabled on and which networks will be advertised.
It would be really appreciated if you rated responses to your posts.
