Hi JC,
Nope, thats not right. The whole concept of 6to4 tunnels is that the
tunnel endpoints can be on diff subnets (as long as there is ipv4
reachability between the two edge routers)
I can ping from R2 to R3.
btw I figured out the problem, i had a static route on R1 'ipv6 route
::/0 e1/0', I changed that to 'ipv6 route ::/0 2002:c800:0001:1::2' and
everything is fine.
Which brings me to another question, any caveat in static routes with
ipv6 which says connected interfaces cannot be used?
Thanks
Rohan

Hi R,
From what I understand and according to your description your tunnel
interface ipv6 addresses is On R2
2002:c800:0001::1/64
On R3
2002:c900:0001::1/64
As you can see they are not on the same subnet...
Change on R2 tunn to 2002:c900:0001::2/64 and with the proper static
routes it should be fine...
Let me know if I'm of my rocker...
Cheers
JC

Hi,
I am unable to figure out one part of this feature
R1----R2------(ipv4 cloud)-----R3---R4
The ipv4 uplink on R2 is 200.0.0.1 i.e c800:0001 The ipv4 ulink on R3 is
201.0.0.1 i.e c900:0001
The ipv6 address on R1 is 2002:c800:0001:1::1/64 The ipv6 address on R2
is 2002:c800:0001:1::2/64 for the physical link and 2002:c800:0001::1/64
for the tunnel
The ipv6 address on R4 is 2002:c900:0001:1::1/64 The ipv6 address on R3
is 2002:c900:0001:1::2/64 for the physical link and 2002:c900:0001::1/64
for the tunnel
I can ping to 2002:c900:0001::1(R3) and 2002:c900:0001:1::2(R3) from R2,
which means the tunnel is functioning.
However I cannot ping to 2002:c900:0001::1(R3) and
2002:c900:0001:1::2(R3) from R1, despite having a default ipv6 route
(::/0) on R1 pointing to the physical link between R1-R2.
Am I doing anything wrong?
Thanks
Rohan
