Hi chaps,
What's the difference between running "tunnel mode ipv6" and "tunnel mode gre ipv6"? I'm working on a rented rack so I can't sniff.
Both appear to work as long as each side is running the same mode, but not intercompatible. Both encapsulate in IPv6 but I don't get the need for two methods of doing this.
I guess the easy answer is that the latter encapsulates into GRE before encapsulating into IPv6 - if that's the case, then why would anyone use that option which I assume adds extra size to the headers?
Can't find much on the Cisco site or Google other than this: Static tunnel interface configured to encapsulate IPv6 or IPv4 packets in IPv6.
Anyone help me out here? What am I missing?
THANKS!
