With four routers in the core running ISIS Multi-topology for (IPv4 and IPv6) on all interfaces and the loopbacks, i can see all the necessary routes for IPv4 but not IPv6.
Despite enabling address-family for IPv6 and multi-protocol under the ISIS process and "ip router isis" under all the interfaces as needed, i still cannot see any IPv6 route when "show ipv6 route isis" is executed.
Can someone please help me out with what might be the problem?.
The topology can be seen on "CCIE-SP-v3.0-Sample-Lab-Part-1-7.pdf" submitted byVincent somewhere last year, " I am reffering to Routers 2,7,8 and 9 in particular" moreso, i am only running the LAB in pure IOS and not XR.
Thanking all in advance,
