Configuration Exercises

1:

Table 10.6 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 authentication between all routers in area 2 of Table 10.6. Use the password "Eiffel" between routers D and E; use the password "Tower" between routers D and F.

3:

Configure level 1 authentication in area 1 of Table 10.6. Use the password "Scotland."

4:

Configure level 2 authentication on the routers in Table 10.6. Use the password "Vienna."

5:

Configure the L1/L2 routers in areas 0, 1, and 3 in Table 10.6 to summarize their area addresses.
