routing experiment of ipv6 somehow not working.

Mon Nov 17, 2014 1:40 pm

so I set up the environments consisting of 5 VMs 1 DNS with 2 clients and 2 routers.
Here is the configurition:
/10.0.1.2(dns)/10.0.1.3(c1) 10.0.1.1(r1) <-> 10.0.2.1(r1) / 10.0.2.2 (r2) <-> 10.0.3.1 (r2)/10.0.3.2(c2)

Everything went ok. ipv4 routing was established and can ping from client1 to client2.
But with ipv6, the pinging from client2 can not get past router1:

From client2 can ping both of router 2 interfaces:
/2001:db8:0:3:8dfa:3a09:aba2:6f55 / 10.0.3.1
/2001:db8:0:2:5c3e:8cc3:5161:cd35 / 10.0.2.2

But, from client2, can not ping IPv6 portion of router 1 interface 10.0.2.1 /db8:0:2:15ec:47a4:3e5a:4861/
I double checked everything to make sure everythign is setup correctly and setup following ipv4/ipv6 address assignment table.

I am wondering what i have to check.

I'm not sure either, other than to suggest to check the IPv6 routing table in the each of the routers.
I also don't know anything about using Win 2008 as a router, but maybe you have to enable the IPv6 routing process.
For example, with a Cisco router the global configuration command ipv6 unicast-routing has to be issued if it is not on by default.
