Routing TCP[s]IP (Vol. 11998)

 
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.
