Good Evening All,
I am prepping for the ICND2 exam.
I am working on a Packer Tracer lab which is attached. The lab is LSG02-PTSkills3. I have 103 of 104 items completed. I am missing one route needed for the ISP router and I can not figure out where I am wrong. I have tried just about every combination for this final route. Can anyone steer me in the right direction?
The task is: ISP should have seven static routes. This will include the three WAN links between HQ and the branch routers B1, B2, and B3.
I believe the only route left is for Web Server.
With that said I have tried the following routes and neither was correct:
Ip route 188.8.131.52 255.255.255.252 s0/0/0
Ip route 184.108.40.206 255.255.255.252 fa0/0
Ip route 220.127.116.11 255.255.255.252 s0/0/0
Ip route 18.104.22.168 255.255.255.252 fa0/0
Ip route 0.0.0.0 0.0.0.0 s0/0/0
Any help or direction would be great.
The PT file you attached has most of the interfaces on most of the routers administratively down. Do you have a saved copy of the lab at the point where you are trying to complete the final steps?
Good news, found it.
The route to B3's address space should be:
ip route 172.20.0.0 255.255.128.0 Serial0/0/0
It was misconfigured on the ISP as a route of:
ip route 172.20.0.0 255.255.192.0 Serial0/0/0
When I replaced that route and ran the check, it showed as 100% complete.
Thanks so much! Can't believe I overlooked that. Very much appreciated!
Question regarding RIP. If you are configuring RIP on a router with four networks connected to it do you need to specify each of the four networks or only two networks? I ask because I am again working on a packet tracer lab and after I specify the first to network subnets 10.1.0.1 and 10.1.4.1 it counts that part of the lab correct. If I specify less than two it counts it as incorrect.
I am guessing either the router picked up the address scheme based on the first two provided or these packet tracer labs are wrong and not simulating real life functionality?
RIP network statements are classful (for all versions of RIP).
When we include the 10.x.x.x, the router says OK, class A 10 net. Any interfaces that begin with 10.x.x.x are included in RIP, along with the real networks associated with those interfaces (/9, /12, etc).
Try this, put in a network statement of 10.1.0.0, then do a show run. On real IOS, it will change it to a 10.0.0.0, because it doesn't care what bits are on outside of the default boundary for that class A address.
