IS-IS Multitopology



Task Requirements:
+++++++++++++++

> Establish the connectivity within ISIS area as per Topology and Addressing. 
        Ensure All Routers are L2 Only routers.
> Ensure R5 Can Ping R1's Loopback0s IPv4 address as well as IPv6 address 
        with source as it's own loopback0. 
> Ensure IPv4/IPv6 traffic follows optimal path.
