Must have been old (very old?) code when I first tried this. 12.4(15)T
doesn't seem to care.
But it still doesn't allow transitional addresses:
gw(config-if)#ipv6 address 0::101:101/96
%FastEthernet0/0: Error: ::184.108.40.206/96 is invalid
gw(config-if)#ipv6 address 0::101:101/128
%FastEthernet0/0: Error: ::220.127.116.11/128 is invalid
If I cannot set an IPv4 address like that, the tunnel won't work. DHCPv6
requests end up outside the tunnel. (it's been many months since I messed
with it, so the interface isn't in the config anymore, but the IPSEC setup
still is :-)) I can send you the packet dumps if you want to scratch your
head over it.
