Section 2.1 OSPF (10 Points)
If you configured this correctly as shown in Example 6-21 through Example 6-26, you have scored 4 points.
If you configured this correctly as shown in Example 6-22 through Example 6-27, you have scored 2 points.
If you configured this correctly as shown in Example 6-22 through Example 6-27, you have scored 2 points. This is a basic OSPF configuration. The idea is to make you more familiar with the OSPF configuration especially adding routing on the Catalyst 3550. Example 6-22.

If you configured this correctly as shown in Example 6-29, you have scored 2 points.
If you configured this correctly as shown in Example 6-29, you have scored 2 points. This is a basic setup to have R2 receiving EIGRP routes from BB1. An important thing is to observe and follow the EIGRP AS number given on the IP IGP diagram. Pay attention when configuring redistribution to explore the redistribute command to ensure that no networks will be missing. NOTE To have R2 to advertise the OSPF networks to BB1, we need to configure under the EIGRP process the network 160.10.0.0. Example 6-29.

If you configured this correctly as shown in Example 6-30, you have scored 2 points. An access list permiting only those two networks and applying under the EIGRP process with a distribute list accomplishes the requirement. It is important to notice that at this point you might need to clear all the routing tables within all routers to have a fast convergence to see only the two networks, considering you have already updated the routing tables with all EIGRP backbone routes.

To adjust the invalid timer, you need to use the timers basic update invalid holdown flush command and configure 200 seconds to the invalid portion of the command. You can leave the other values as the default values. If you configured this correctly as shown in Example 6-33, you have scored 3 points. Example 6-33.

Notice that to establish level 1 and 2 adjacencies you do not need to configure the isis circuit-type interface command or is-type router process command because this is the default. If you configured this correctly as shown in Example 6-34, you have scored 2 points.
If you configured this correctly as shown in Example 6-34, you have scored 2 points. This is a basic IS-IS configuration into a single area. It is a good idea to configure your R6-loopback address under IS-IS because R6 is running only IS-IS and you might need to have R6-lo0 be reachable later in the lab. Example 6-34.
