I'm recently working on a project, in which we are provided two network one with IPv6 Connectivity only and other with IPv4 Connectivity only. These two networks are connected to each other with a switch(i.e., Cisco 4503 which also works as router) and our task is that, we have to configure that switch/router in such a way that a IPv4 host can send packet to IPv6 host and vice-verse. I have try all the tunneling, but in all of them IPv6 can only be connected to IPv6 host only not with IPv4. I need your help in this that how can i made router configuration so that it should be possible to connect two Different Host with different IP versions i.e., one with ipv4 and other with ipv6.
thanks in advance
