I  am new to VCS. :) so have a basic doubt.
 
Can the VCS heartbeat across a network  or in  other words through a router ?

Vcs  uses LLT aka veritas protocol and it is connection less ..... but yes vcs uses llt over a network

example usually u have 2 high prioity links and both usually on there own vlan

LLT is a non-routable protocol -- it cannot span routers.
Norm is to create a dedicated vlan for GAB/LLT traffic, I've even seen separate vlans for each cluster.
Two node-clusters can be set up using cross-over ethernet cables, but the VLAN way allows for better ability to scale.
