Hi all,
      I have a doubt regarding ipv4 over ipv6 tunnel.

1. When a tunnel is configured,  we configure source and 
destination for the tunnel. Why source address should be 
configured for the tunnel. Is it not sufficient to configure only 
destination address for the tunnel.

2. is it necessary to establish the path between source and 
destination explicitly before establishing a tunnel and then use 
this path in routing header of tunnel packet for transmitting the 
packet?.


thanks in advance

regards
ari.
