I need to be able to run more than one BGP routing process on my lab router. I have over connected BGP routers connected to my live production network and I need to emulate the production network with GNS3. However, BGP rules only allow a single BGP routing process on a single router. how to overcome this limitation for my lab?

View 2 Replies View RelatedAs my original Innbox V50U modem/router does not have a strong enough wifi signal I had to add in an additional wifi router - I used a Cisco Linksys E4200.The problem is that if I connect my laptop to the cisco router I can see the Innbox router but not vice versa. There is an additional problem as I have a wireless printer that is connected to the Cisco router. If I connect to the Innbox router I cannot use this printer as I cannot see its IP address.I read somewhere it might be down to the subnet mask. both are set to 255.255.255.0Apologies if this is n00b stuff but I have not had this problem before, I just naturally though the two networks would be able to talk to each-other.
View 1 Replies View RelatedI will be adding wireless access points or repeaters on a business network. The business already has one wireless router using a https login, that 15 computers are wired to, through switches. This Secure http router is directly connected to the cable modem.Would I be loosing the benefit of Secure http by adding wireless access points or repeaters that don't support it? Or would they be securely routed by the main https router connected to the gateway?I have never had the opportunity to work with a secure http router before.

View 4 Replies View RelatedWe have small which I'm looking to implement and have built this on GNS3.
We have:
Router A in site 1
Router B in site 2
Router C in site 3
Router A and B are connection via a point to point 100M link and from Router C we have a 2 point to point one of which is 5Mpbs and going to Router A and Router B.
For Router C to reach Router A network it will go via Router B and these are 100M connection. When the link between Router A and B goes down. Router C should update and start using the 5m route.
For some reson, the routes are not updating. I have to do 'clea ip eigrp ne' for the routes to update and if I reload the routers all works well, it seems the problem is intermittent.
Can a router connect to a switch to gain additional ports (to both access the internet AND to maintain an internal / home network)?IP line to house, connected to modem, connected to 4-port router, connected to 8-port switch. Now, each of six rooms in my house has one Cat-5e (RJ-45) jack whose run terminates to the switch. In some of these rooms, I need two wired devices (wireless isn't an option for the devices). Can I use the LAN port of a spare, wireless router (to also use as an access point for cell phones, etc) to plug into the jack and increase the number of ports in that room to have a functional LAN and WAN? I have read tons of info on plugging switches into routers to increase the number of ports, but not the other way around. Plus, ripping open walls to expand the network isn't feasible either. My other thought, would be to replace the switch with another (2nd) router, by connecting the 1st and 2nd routers together, and have the runs terminate to the open LAN ports of both routers --= and then expand the ports in those rooms by also using additional, spare wireless routers.

View 2 Replies View RelatedI'm using a SMC2804WBRP-G router connected to my ADSL-modem. Usually there are two computers connected to this router: a win7 ultimate desktop(wired) and a macbook air (wireless). Both working absolutely fine and never caused any connection drops as far as I know.
A new room mate moved in last month and each time she starts up her win7 home laptop the router looses the internet connection. The laptop is on a wired connection.
The first time she connected to my router, the connection dropped every 2 mins. To find out whats wrong with her machine I disabled all unnecessary services etc. besides the anti virus software. That worked to eliminate almost all of those periodic connection drops. But the start up drop remained and I've got the feeling that the router is still loosing connection from time to time.
I have a 2821 router and need to add another Ethernet port.
However, all the Ethernet modules seem to be End of Sale and the suggested replacements are only compatible with the ISRg2 range.
I have AT&T Uverse which provides Internet for my home. The wireless capability of this router is pretty bad, I don't get good/reliable wireless reception upstairs in my office. The solution was to buy a Cisco E2500 and add it as an access point upstairs.
I have the E2500 LAN port connected to the LAN port of my uverse router downstairs. DHCP is turned off on the E2500. I have my office PC wired into the E2500. The home PC works fine, its getting DHCP from the uverse router downstairs and connects and good speeds. The problem comes with my wireless devices trying to connect to the E2500.
I should mention that yesterday when i bought this, all worked fine. This morning when I came into my office none of the wireless devices would connect to the E2500 at all. But as soon as I remove the cable that connects the E2500 to the uverse router downstairs they will connect via wireless but of course not get an IP address since that is disabled.
I have factory reset the E2500 and uverse router several times and am getting no where. what could be causing the wireless devices to not connect at all?
I have an issue with 7600 router where CPU goes up to 60-70% and memory is also high. Both due to BGP Router process. URL We are seeing this issue since ISP has upgraded their router 20 days ago.

I want to ping my GNS3 routers from my real LAN PCs. Right now I am able to ping those GNS3 routers from real PC on which GNS3 is installed. The network topology is something like this.
