Hi All, I am not able to understand why the IPv6 tunnel is a unidirectional mechanism as specified in section 3 of RFC 2473. Here is the text which is not making sense to me.
=== An IPv6 tunnel is a unidirectional mechanism - tunnel packet flow takes place in one direction between the IPv6 tunnel entry-point and exit-point nodes (see Fig.1). <snip> Bi-directional tunneling is achieved by merging two unidirectional mechanisms, that is, configuring two tunnels, each in opposite direction to the other - the entry-point node of one tunnel is the exit-point node of the other tunnel (see Fig.2). === Does it mean that we will have to configure 2 tunnels on each end point in order to create a virtual point to point link between the two systems. That's not the case for GRE for IPv4. Help would be highly appreciated. regards Mukesh -- ****************************************************************** It is a mistake to look too far ahead.Only one link in the chain of destiny can be handled at a time. ****************************************************************** Mukesh Gupta Phone: (650) 625-2264 Cell : (650) 868-9111 http://www.iprg.nokia.com/~mgupta ****************************************************************** -------------------------------------------------------------------- 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] --------------------------------------------------------------------
