Hi Ari, > I have a doubt regarding ipv6 over ipv4 tunnel.
I think your questions are pretty generic to any IPinIP tunnels. > 1. When a tunnel is configured, source and destination is > configured. > Is it sufficient to configure destination address only. My means > to say why source address is required. You need to put these source and destination addresses in the tunnel header of the packet. The source address is required so that the router at the other end of the tunnel can send the packets back to the router who tunnelled the packet. > 2.

I don't think that's necessary. You could just tunnel the packet and forward it as a normal IP packet. The tunnelled packet has the outer IP header (tunnel IP header) which is sufficient to forward the packet throughout the path. > 3. I have one more doubt, when there is concept of fast path and > slow path, which functionality of the tunnelling should go to the > fast path and which functionality of tunnelling should go to the > slow path. I think, the tunnel processing (encapsulating the packet in another IP header) should be done in slow path. regards Mukesh -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
