RIPv2 Troubleshooting Sim

October 16th, 2016 Go to comments

Refer to the topology below and answer the questions using “show” commands.


Question 1

Server1 and Server2 are unable to communicate with the rest of the network. Your initial check with system administrators shows that IP address settings are correctly configured on the server side. What could be an issue?

A. The VLAN encapsulation is misconfigured on the router subinterfaces.
B. The Router is missing subinterface configuration.
C. The Trunk is not configured on the L2SW1 switch.
D. The IP address is misconfigured on the primary router interface.


Answer: A


Check the configuration of the interface that is connected to Server1 and Server2 on R2 with “show running-config” command.


We see that subinterface E0/1.100 has been configured with VLAN 200 (via “encapsulation dot1Q 200” command) while Server1 belongs to VLAN 100. Therefore this configuration is not correct. It should be “encapsulation dot1Q 100” instead. The same thing for interface E0/1.200, it should be “encapsulation dot1Q 200” instead.

Question 2

Users in the main office complain that they are unable to reach internet sites. You observe that internet traffic that is destined towards ISP router is not forwarded correctly on Router R1. What could be an issue?

Ping to Internet server shows the following results from R1:

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to, timeout is 2 seconds:
Success rate is 0 percent (0/5)

A. The next hop router address for the default route is incorrectly configured.
B. Default route pointing to ISP router is not configured on Router R1.
C. Default route pointing to ISP router is configured with AD of 225.
D. Router R1 configured as DHCP client is not receiving default route via DHCP from ISP router.


Answer: B


When all the users cannot reach internet sites we should check on the router connecting to the ISP to see if it has a default route pointing to the ISP or not. Use the “show ip route” command on R1:


We cannot find a default route on R1 (something like this: S* [1/0] via so maybe R1 was not configured with a default route. We can check with the “show running-config” on R1:


We need a default route (like “ip route”) but we cannot find here so we can conclude R1 was not be configured with a default route pointing to the ISP router.

Question 3

Examine R2 configuration, the traffic that is destined to R3 LAN network sourced from Router R2 is forwarded to R1 instead R3. What could be an issue?

R2#traceroute source
Type escape sequence to abort.
Tracing the route to
VRF info: (vrf in name/id, vrf out name/id)
1 0 msec 1 msec 0 msec
2 !H !H *


A. RIPv2 enabled on R3, but R3 LAN network that is not advertised into RIPv2 domain.
B. RIPv2 routing updates are suppressed between R2 and R3 using passive interface feature.
C. RIPv2 not enabled on R3.
D. No issue that is identified; this behavior is normal since default route propagated into RIPv2 domain by Router R1.


Answer: C


First we should check the routing table of R2 with the “show ip route” command.


In this table we cannot find the subnet “” (R3 LAN network) so R2 will use the default route advertised from R1 (with the command “default-information originate” on R1) to reach unknown destination, in this case subnet -> R2 will send traffic to to R1.

Next we need to find out why R3 did not advertise this subnet to R2. A quick check with the “show running-config” on R3 we will see that R3 was not configured with RIP ( no “router rip” section). Therefore we can conclude RIPv2 was not enabled on R3.

Question 4

What is the correct statement below after examining the R1 routing table?

A. Traffic that is destined to from R1 LAN network uses static route instead RIPv2 because the static route AD that is configured is less than the AD of RIPv2
B. Traffic that is destined to from R1 LAN network uses RIPv2 instead of static route because the static route AD that is configured is higher than the AD of RIPv2
C. Traffic that is destined to from R1 LAN network uses static route instead of RIPv2 but the traffic is forwarded to the ISP instead of the internal network
D. Traffic that is destined to from R1 LAN network uses RIPv2 instead of static route because the static route AD that is configured is 255


Answer: B


Surely we have to use the “show ip route” command to check the R1 routing table.


As we see here, 10.10.10/24 is learned from RIP. Notice that although there is a static route on R1 to this destination (you can check with the “show running-config” on R1 to see the line “ip route 200”), this static route is not installed to the routing table because it is not the best path because the Administrative Distance (AD) of this static route is 200 while the AD of RIP is 120 -> R1 chose the path with lowest AD so it chose path advertised via RIP.

    bulud, Yes I repass my exam yesterday and I M CCNA :)
    I had 54 Q&A lab 6labs!!! (OSPF ipv6, ACL, ACL2, EIGRP troubleshoot SIM, RIPv2, GRE multilink)
    All was same only EIGRP toubleshoot all Q&A are same but configuration changed so other answers :
    1)The loopback interfaces on R4 with the IP addresses of, and are not appearing in the routing table of R5. Why are the interfaces missing?

    Which path does traffic take from R1 to R5?
    I said R3 I think

    Router R6 does not form an EIGRP neighbor relationship correctly with router R1. What is the cause for this misconfiguration?
    Do show ip protocol then the default value must be K1=1;K2=0K3=1;K4=0;K5=0; so = 10100
    and when you see that was something like : 00111
    A. The K values mismatch.

    Why are the pings failing?
    The IP address that is configured on the Lo1 interface on R5 incorrect.
    because when you do show ip int brief you see : but the address must be

    but it was very easy only show run and you see ip add or EIGRP is incorrect into the multi link

    else all was same I have a PDF 45Q&A that was all in my exam give your address mail I can send you

    Is there any other way to see floating static route besides show running? I tried show ip route static, but nothins appears (I built similar lab in Packet Tracer). Thanks in advance

    can somebody tell me lab questions are not corelated because , in question 2 in this lab it was mentioned that there’s no default route on R1
    but in question 3’s answer its mentioned that R3 is getting its default route from R1 but R1 dont have a default route according to question 2
