ipv6ip tunnel keepalive

Hi. I'm trying to see if KEEPALIVE mechanism that works on ipv4 GRE tunnels is also operative in ipv6ip tunnels. Although you can happily configure keepalive params in the interface, I can't see any effect (or even keepalive traffic) on both tunnel ends, so please if anyone can give me some hint/advice about what IOS or equipment is known keepalives works for ipv6ip tunnels, or even if this has been documented somewhere that it work/don't work, that would be really great.

Sincerely, it doesn't make me much sense to have interfaces that are always up (even when you shut down the other end)...

No, it won't because the protocol doesn't support them.

Just send ICMPv6 packets to the machine at the other end. That is what SixXS (see "

formatting link
") use to monitor the remote ends of the tunnels they provide.

Kind regards
