I notice that in the newer kernels, support for RFC 4798 has been added through the means of IPV4 mapped addresses. I do have a route pointing to the mapped address being the nexthop and I'm unable to ping the routes.
route added
abcd:4003:0:1::/64 encap mpls 2/300016 via ::ffff:3.3.3.3 dev eth12 proto 22 metric 1024 pref medium
I get the below error thrown when tried to ping:
ping6 abcd:4003:0:1:abcd:1:0:5
connect: Address family not supported by protocol
also made sure i have a v4 route to 3.3.3.3 which is reachable
3.3.3.3 encap mpls 300016 via 192.168.1.2 dev eth12 proto 22
Does the kernel automatically translate the mapped address or has this support not yet added?
under sysctl -a , i see ipv6 is enabled and even allowing for mapped address is enabled.
net.ipv6.bindv6only=0 and net.ipv6.conf.all.disable_ipv6=0)

Hmm. That's the error you normally see if someone had disabled IPv6 system-wide on the system, e.g. by setting the disable_ipv6 sysctl or blacklisting the ipv6 module. Check that someone hasn't done anything to disable IPv6 on the system, even partially, or for a single interface.
