restricting traffic from 1 router to 2nd by config acc-list on 3rd

[s.m]

Greetings........

Imagine a network of 3 routers;x,y,z connected in a triangle kind of a mesh.

X

Y Z

X connected to Y connected to Z connected to X back again.

What i hope to know is ; is it possible for me to

"restrict" the ethernet/LAN of Y from accessing LAN of Z & vice-versa, by putting an access list in router X.

(consider that all ips in either LANS are all public/legal ips)

If the answer is "YES" , kindly explain the logic as to how it will work.

Appreciation is advance.....

More than likely this can be done with access lists but they may be a little complex in a fully meshed network. You are probably better off looking at a firewall solution and then you can be very specific about what traffic to allow. Talk it over with your technical support people.
