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
