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.
