---------------------------------------------------------

now users on remote location can able to reach the vlan 3 machines?i think YES

is the setup correct or anything else to be changed?

router eigrp 4444 network is correct? if not do i need to specify the subnet also? i don't think so, but still doubting.

Re: VLSM across WAN

The users at the remotes should be able to get to the machines on VLAN 3, but it looks like you ahve static and eigrp routes configured. You only need one. This link should help with the eigrp.

http://www.cisco.com/en/US/products/sw/iosswrel/ps1831/products_configuration_guide_chapter09186a00800d97f8.htm

The only other thing is default routes. If you need any of these machines ot get somewhere unknown all the routers will need default routes.

Re: VLSM across WAN

the link you have specified, sayz page not available or it has been moved, can you send me the appropriate link.?
