Troubleshooting – 2 Points
It’s the little things that throw you off. My wife has my laptop so I’m using an old desktop to complete this lab. The position of the control key is different than any other keyboard that I use. So every time that I break out of configuration mode cntl+z or go back to the access server cntl+shift+6 x, I’m tripping over myself. Yet another good lesson before the lab.
There are faults to find in this lab. I found the first error in my initial examination of the network (checking that all interfaces are configured per the lab diagram and looking anything funky in the initial configurations):
1) Incorrect mask on r3’s fa0/0 (should be /24 and not /25):
r3#sh run int fa0/0
ip address 220.127.116.11 255.255.255.128
The second error was found later on in the lab. I overlooked this because although the interface did not have an IP address configured, sometimes this is by design as you are asked to configure it later in the lab. As it turned out I needed to make a couple of changes to bring up VLAN23.
2) r3’s fa0/1 is not configured with an IP address
r3(config-router)#do sh run int fa0/1
no ip address
r3(config-if)#desc ->r2 vlan 23
r3(config-if)#ip add 18.104.22.168 255.255.255.0
r3(config-router)#do sh cdp neigh fa0/1
Capability Codes: R – Router, T – Trans Bridge, B – Source Route Bridge
S – Switch, H – Host, I – IGMP, r – Repeater
Device ID Local Intrfce Holdtme Capability Platform Port ID
sw3 Fas 0/1 176 R S I WS-C3560- Fas 0/3
Need to add vlan 23
sw3(config)#do sh run int fa0/3
I need to assign this port to VLAN23:
sw3(config-if)#swi acc vla 23
r3(config-router)#do p 22.214.171.124
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 126.96.36.199, timeout is 2 seconds:
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms
The interesting thing about this section is that the IE solution guide shows the second error as r3′ s Frame Relay interfaces being flopped. My initial configuration did not contain this error.
