Thank you for the detailed info.
After some investigation I believe the problem is in the particular
choice of the IPv6 addresses.
First I used the Linux "ip" command to add the route and I got
exactly same error which suggested to me that the problem is not
XORP-specific:

root at ixp[54] ip -f inet6 addr add 10:10:10:10:10:10:10:10/64 dev eth1
root at ixp[55] ip -f inet6 route add 10:10:10:30::/64 via 10:10:10:10:10:10:10:20
RTNETLINK answers: Invalid argument
Exit 2

In fact, if you check the following table with the assigned IPv6
addresses, you would see that the 10:10:10:10... addresses fail
within the 0000::/8 address range which is reserved by IETF:
http://www.iana.org/assignments/ipv6-address-space

In fact, if you replace the first two octets of the interface
addresses with 2010: instead of 10: then everything works as
expected:

interfaces {
    interface eth1 {
        vif eth1 {
            address 2010:10:10:10:10:10:10:10 {
                prefix-length: 64
            }
        }
    }
}

fea {
    unicast-forwarding6 {
        disable: false
    }
}

protocols {
    static {
        route 2010:10:10:30::/64 {
            next-hop: 2010:10:10:10:10:10:10:20
        }
    }
}
