Shafeen,
If the question is about IPv6 fully meshed tunnels between routers and no
mention of hosts, I will think more of 6to4 tunnels before considering
ISATAP tunnels.
Though both share some similarity in that, they are both point-multipoint
(NBMA) auto-tunnel creation methods. But ISATAP, is mainly used within a
single IPv6 site to provide transportation for sparse IPv4/IPv6 hosts
(sometime like one dual-stack windows PC want to talk to another dual-stack
windows PC over your IPv4 network and you do not want to be creating tunnels
all over the place, ISATAP will be a good fit here); while 6to4 is used
between isolated IPv6 sites to interconnect those sites together over an
IPv4 infratructure (sometime like some IPv6 isolated border routers, want to
talk across the IPv4 network to other isolated IPv6 routers, and you do not
want to be hopping from router ro router to configure multiple tunnels, 6to4
will help to create that type of 'full mesh' feel without the administrative
overhead.)
Since, the CCIE (R/S) lab blueprint have not indicated the presence of
IPv4/IPv6 hosts in the lab, it is very unlikely to encounter ISATAP tunnels,
but with six able and willing routers lying around in the your lab pod, 6to4
tunnels are fair game.
Thanks.
