Cisco :: Router 6 Cannot Communicate With 0
Jan 21, 2012
I tested ospf multi-areas in packet tracer as shown in attached file.(Sorry I don't know how to upload the lab image.)There I got a problem that router 0 in area 1 and router 6 in area 3 cannot communicate.Except this, router 0 can communicate with other routers and the same to router 6. I have made a virtual link between backbone,area 1 and 2 ABR router 1 and area 2,3 ABR router 4.I use process id 123 for every area. But when I type "show ip route" in router 0, it is shown [code] when it is typed in router 6, it is shown [code] So, router 6 cannot communicate with router 0.I don't wanna make a static route to 1.0.0.0 network in router 6.

My basement doesn't get a good wireless signal. It doesn't affect my computer since it's hardwired via a couple of Asoka PlugLinks. However, I've always had bad signal reception from my main router which is two floors above. Because of this, I was rarely able to connect my Wii to the internet and am now unable to connect my Wii U to it either.Recently I purchased a new wireless router (a Linksys e1200n) to speed up the network. So, having a spare router (the old router: a Linksys WRT54G), I decided to try to convert it to an access point in the basement so the Wii U could finally get a stable internet connection (it's very picky about signal strength for some reason). I reset the old router and followed some instructions on how to make it an access point instead of a router. Once it was configured I bought another Asoka PlugLink and placed the WRT54G in the basement. I connected the PlugLink to the wall outlet and connected the Ethernet cable to LAN port 1 on the WRT54G. I thought everything would be fine, but then the problems came.
My Wii U was unable to connect to it. I also tested a couple of laptops and they were able to connect to it, but they couldn't access the internet. I assumed maybe distance from the main router was the cause(a PlugLink is connected from LAN port 1 on the back of the main router into a wall outlet, linking other PlugLinks to it), but my computer's PlugLink is in the same room and has no problems connecting.

I have two VLANs set up on a Catalyst 2950 switch: VLAN 1 (192.168.1.x) and VLAN 2 (192.168.2.x). VLAN 2 can ping the router on the 192.168.1.x network and nothing else, which is what I want. However, computers on the 192.168.1.x network can ping computers on VLAN 2, which is what I do not want. I want to make it where VLAN 1 and VLAN 2 cannot communicate with one another, but that VLAN 2 can still ping the router on VLAN 1. I've read about access control lists and ip tables

I am just confused over the fact that a router configured with 10.1.1.1 address (assuming it's got 255.255.255.0 mask) can communicate to a PC connected to one of it's LAN ports and manually setup to have 10.1.1.2/8 address. I was sure that since these are two different subnets they won't see each other. But they do and searched wiki and just googled to see why, but with no success. A friend of my friend says something about 'same range' but it makes little sense to me.
I just need a good article about it or a crystall clear explanation, because I feel my understanding of IP is not as good as I used to believe.

Any way to force the router to communicate wirelessly at only 1 or 2 Mbit/sec? I am having trouble connecting to another device, not made by Dlink, and their technical support suggested testing at a lower data rate.

I was asked to configure a new ASR 1002 today and after successfully puttintg the config on the router (via TFTP) the router will no longer communicate with anything. There is nothing in the config to cause this (it was actually pulled off a working production ASR 1002) and I am unable to ping a local loop back IP while consoled into the router?? I removed the config, reloaded the router and configured a new loop back - same issue cannot ping the loop back or anything else connected to this router.

I've had a dlink604router connected to a dsl modem for the longest time with all my computers receiving internet without any problems. I just switched to a cable modem and the router blinks as if it's communicating with the modem but no internet is getting to the computers connected to the router. I've always left the dlink's settings to default-my 2 macs receive automatic dhcp. If the settings on the dlink have to be changed to communicate with the new cable modem?

I have been trying to connect my daughter's toshiba a215-54697 wirelessly to my linksys e3000 router. The computer recognizes the network wirelessly as the correct name and will only have "local access". When it is hardwired to the router it connects just fine, it also will connect to the unsecured (guest)network. I have comcast internet that is connected to an ooma box that is cconnected to the router. My laptop and the playstation find and connect to the internet just fine. The toshiba is running windows vista with a atheros ar5007eg adapter.

Been using a BEFSR41 with a Speedstream 5200 modem for 7 years with 3 Apple computers. The modem is outdated for todays speeds. Windstream gave me a “new” modem Gagaset 4300. After configuring the 4300 I replaced the 5200 with the 4300. With this setup the computers are not able to connect to the internet. The LED lights on the router do light up and the computer’s networks show there is an ethernet connection but no joy when I try to launch a browser or get email However I could connect the 4300 directly to one computer and get email and search the web. The Windstream tech (phone call) said the router needs to be reconfigured so it can “talk” to the 4300 modem. If this is true how can I configure the router if I cannot get to the Linksys -router web pg?

My friend and I bought Acer Aspire 5741's about 9 months ago and neither of us has had any problems until now. My friend went to connect to the internet via wireless router yesterday to find that there was limited connectivity (no internet access). We assumed it was a router issue and I gave her a number of things to check but all seemed ok with it. I went to her house to look at it today and when I ran the connection troubleshooter got "windows can't communicate with.......... (DNS server)". I connected my laptop via her router and everything was fine. I brought her laptop back to my house and tried to connect to the internet via my router and got exactly the same 'DNS' message - my laptop again connected without any problem.
I have re-booted the routers, laptops, network adapters etc and also checked the wireless adapter settings on both laptops, which appear to be the same. I have re-set the TCP/IP stack and have also tried ipconfig /release and /renew - none of which seems to have made any difference. the results of the tests are as follows (linksys is the SSID in use):

I have an skill exercise with 4 Routing Protocols Default Route,Static Route,Eigrp, Ospf. I have about 6-7 routers, and each of them has an routing protocol. But the problem is the Main router INTERNET, which it has to use Static in a direction, and default in the opposite path. This is the scheme of routers and how the r.protocol have to be configured.

I recently set up our new Cisco Linksys E1000 router (we originally had a Belkin, but it is dying). It works perfectly fine on my desktop. However, there is only a "local connection" on my mom's laptop, a Toshiba Satellite running Vista. Diagnosis: Cannot Communicate with Primary DNS Server (68.105.28.12). I've read a bunch of other posts on many websites but so far nothing has worked.

I have two routers in my office, each one having wireless extensions and its own DSL connection.I want machine on A subnet communicate with machine on B,I'll need some sort of physical connection (a cable? a new device?).Router A and B are typical home router with wifi extension: they only have a WAN port,I won't be able to let them talk to each other simpy by plugging an Ethernet cable between two LAN ports, since the two routers are on different subnets.

Problem: No internet connection. 'Can't communicate with primary DNS server'Information: I am using a Windows 7 64 laptop (LAN connection) to connect to the internet. Two days ago this stopped working (after working fine for 3 months). Using windows troubleshoot I receive the message 'Can't communicate with primary DNS server'. I have checked the IPv4 and IPv6 and they are all set to automatic.I then tried to reset this using Microsoft 'fix it solution' as indicated Can't communicate with Primary DNS Server this still had no luck.I have also tried,
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog
Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log
Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log
and ipconfig/ release and ipconfig/ renew none of this has made any difference. I can successfully ping the default gateway but cannot ping google. All packets time out.Additional information: Using an older laptop I am able to successfully connect to the internet on the same line. Also the laptop that is not working does work fine at work. So I don't even know if the problem is with the hub or the laptop.

I'm having an absolute nightmare trying to get my laptop to connect to the internet. It will connect to our home network (virgin media cable broadband) locally but won't connect to the internet. I've tried a few of the fixes I've read on here such as changing the DNS settings myself but it's going nowhere.I can connect to other networks for example my parents virgin media network and the other laptops and my ps3 can all connect to our internet just fine so I really don't understand why mine isn't working.When I diagnose the problem it says "Cannot communicate with Primary DNS Server (194.168.4.100)" and underneath it says "Network diagnostics pinged the remote host but did not receive a response"
