Table 10-8 shows the interfaces, interface addresses, and subnet masks of 11 routers. The table also designates that routers belong in the same area. Write Integrated IS-IS configurations for the routers, using the following guidelines:
Make up your own System IDs for the routers.
Use the shortest NETs possible.
Configure routers as L1, L2, or L1/L2 as appropriate.

Tip: Draw a picture of the routers and subnets first.
2
Configure IPv6 on each router, in multi-topology mode. Use the address 2001:db8:0:x::/64, where x is the hexadecimal value of the subnet (4th octet only) of the corresponding IPv4 address on each link.
3
Configure authentication between all routers in area 2 of Table 10-8. Use the password "Eiffel" between routers D and E; use the password "Tower" between routers E and F. Use type md5 authentication.
4
Configure level 1 authentication in area 1 of Table 10-8. Use the password "Scotland." Use cleartext passwords with no key chains.
5
Configure level 2 authentication on the routers in Table 10-8. Use the password "Vienna." Use cleartext passwords with key chains.
6
Configure the L1/L2 routers in areas 0, 1, and 3 in Table 10-8 to summarize their L1 addresses, both IPv4 and IPv6.
