RIPv1, RIPv2, IGRP, and EIGRP all auto-summarize classful boundaries by default (OSPF does not).To make discontiguous networks work, meaning you don't want classful boundries to summarize, you need to turn off auto-summary.

Here are the Steps for this Lab Solution:
Explanation:
The question states we can't access the router so we can only get required information from
switch building_1. Click on the PC connected with switch building_1 (through a console line) to access switch building_1s CLI. On this switch use the show running-config command: building_1#show running-config Next use the show vtp status command to learn about the vtp domain on this switch building_1#show vtp status (Notice: the IP address, IP default-gateway and VTP domain name might be different!!!) You should write down these 3 parameters carefully. Configuring the new switch
+
Determine and configure the IP host address of the new switch The question requires "for the switch host address, you should use the last available IP address on the management subnet". The building_1 switch's IP address, which is 192.168.22.50 255.255.255.224, belongs to the management subnet.
Increment: 32 (because 224 = 1110 0000) Network address: 192.168.22.32 Broadcast address: 192.168.22.63 ->The last available IP address on the management subnet is 192.168.22.62 and it hasn't been used (notice that the IP address of Fa0/1 interface of the router is also the default gateway address 192.168.22.35). Also notice that the management IP address of a switch should be configured in Vlan1 interface. After it is configured, we can connect to it via telnet or SSH to manage it. Switch2#configure terminal Switch2(config)#interface Vlan1 Switch2(config-if)#ip address 192.168.22.62 255.255.255.224 Switch2(config-if)#no shutdown (not really necessary since VLAN interfaces are not physical and are not shut down but, no harm in doing so and is good practice for physical ports)
+
Determine and configure the default gateway of the new switch The default gateway of this new switch is same as that of building_1 switch, which is 192.168.22.35 Switch2(config-if)#exit Switch2(config)#ip default-gateway 192.168.22.35
+
Determine and configure the correct VTP domain name for the new switch The VTP domain name shown on building_1 switch is Cisco so we have to use it in the new switch (notice: the VTP domain name will be different in the exam and it is case sensitive so be careful) Switch2(config)#vtp domain Cisco
+
Configure the new switch as a VTP client Switch2(config)#vtp mode client We should check the new configuration with the "show running-config" & "show vtp status"; also try pinging from the new switch to the the default gateway to make sure it works well. Finally save the configuration: Switch2(config)#exit
Switch2#copy running-config startup-config

Cisco default encapsulation is HDLC which is by default enabled on all cisco router. If we want to enable other encapsulation protocol(PPP,X.25 etc) we need to define in interface setting. But here except s1/1 all interface defined by other encapsulation protocol so we will assume default encapsulation running on s1/1 interface and s1/1 interface connected with North

Implementing EIGRP http://www.ciscopress.com/articles/article.asp?p=1171169&seqNum=3 Below is an example of the show ip eigrp neighbors command. The retransmit interval (Smooth Round Trip Timer - SRTT) and the queue counts (Q count, which shows the number of queued EIGRP packets) for the adjacent routers are listed: R1#show ip eigrp neighbors IP-EIGRP neighbors for process 1 H Address Interface Hold Uptime SRTT RTO Q Seq (sec) (ms) Cnt Num
