I have a 1721 router with 3 equal routes to 0.0.0.0, using CEF for load balancing with universal load balancing algorithm. It doesn`t NAT, just routing. I wonder which is the maximum capacity of the router, since it should support up to 40000 connections to different destination IP. Is the limit set by the router resources (CPU, memory, ...) or a maximum limit of entries in the table FIB / RIB?
View 7 RepliesWhat is the maximum amount of traffic a 3825 router can take. I know that a 3825 is rated to handle half of a DS3/T3. We are planning to put a 50Mbps point to point metro Ethernet circuit between two 3825's and run encryption over that line. I just want to make sure we don't max out the router as I remember once a customer maxed out a 3825 with a ton or GRE tunnels and the router crashed every time they did their nightly data dump.

Ex: Actually my problem is, i'm using Dlink 8 port switch, and 40 computers connected indirectly to that switch, few times getting issues like packet drops, internet connecting & disconnecting etc. so i want to know either the switch is capable or not.
I have a laptop and a PC, both connected to the same router, connected to a Time Warner Road Runner cable modem. The laptop works fine whether it is in wireless or wired mode. The PC does not have wireless. When the PC is connected to the router, it's download speed is OK but I have zero upload speed - which of course kills my ability to do almost any online or even LAN task, including browsing and file transferring over LAN.When I plug directly into the modem, bypassing the Belkin, the PC connection works just fine. It only encounters errors when going through the router, but every other computer in the household works fine through the router (3 laptops, work great either wired or wireless using same cables and ports as the PC). The PC worked fine in my old apartment with a different router, but as soon as I got to this one, nothing.
Both comp's have WinXP Home Edition. The PC has a Realtek onboard NIC, called PCIe GBE Family NIC in Device Manager. Have tried uninstalling and reinstalling it, and using multiple driver versions, to no avail. The Ethernet cable is known working. The router is a Belkin F5D9230-4 Wireless G Plus MIMO Router with fully updated firmware.All my firewalls are turned off, including that of the router.Everything is up to date, I have done full virus and malware scans, power cycled everything, and I just cannot solve this problem.
Reciently I bought a WRT120N Router to get a better internet connection and to have more capacity to connect different wireless devices, because the modem from my internet provider company is extremely restrictive.
I use an iMac, a Notebook with Windows 7 and a Netbook with Ubuntu 11.04, besides different devices (iPhone, iPod, PS3, Kindle). Although when I configured the router I connected every devices simultaneasly, with better signal quality than before, after using it for a couple of days I found that it disconnects itself, I can't access internet, and my only solution it's to switch it off and on.

View 3 Replies View RelatedMonday, I had a cisco 1750 router in place suddenly stop communicating to a Larscom ISP owned unit. Since then I have sent two replacement 1721 routers with WIC-1ENET cards. I have used the original straight thru cable to connect the 10baset port on the Larscom to my E0 on the WIC-1ENET. No link lights on either. I have also tried a known working straight thru cable and a crossover cable. No link lights.
I can take a crossover cable from a pc and ping the E0 port without issue. The ISP is telling me it is an issue with my equipment.

I have cisco 1721 router so I installed an ethernet interface card so when I make show run I found that there is a fast ethernet 0 and ethernet 0 (which I installed) so i wand to make subinfaces of the etheernet 0 but I can't. I tried to make encapsulation dot.1q but it doesn't accept it.
Is Ethernet0 supported to generate subinterfaces?
Long time since I have had to configure a router and have a small project
Here is what I have in a simple diagram:
PC(static IP)--to--Switch--to--(Ethernet0 int, WIC0)1721 router(FastEthernet0 int, built-in)--to--Switch--to--PC(DHCP)
I need static IP PC to be able to ping the DHCP client. Static IP units 10.1.1.x/16, DHCP clients 10.1.3.x/16.
I have found these overlap and thus give errors and will even shutdown the interface if I enable certain things like routing or bridging.
So I gather I need to change one interface IP range, which would be the DHCP side, I need to stay 10.1.1.x/16 for static side.
enable dot1q encapsulation on two ethernet ports on a 1721 router. I am able to configure it on the built in fastethernet port, but not on any interface provided by a WIC-1ENET or a WIC-4ESW. I have an application that requires two physical ethernet ports that support dot1q encapsulation.

I am working on a backup system for my WAN. Verizon quoted the HWIC-3G-CDMA-V to work with my Cisco 1721 router. I have a bunch on these routers on a shelf and thought I would use them for the 3G network. Looking at the Cisco web site it does not list the 1721 as being able to work with this HWIC. I thought it might not be listed as the 1700 series are End of life. Whether it will work?

View 9 Replies View RelatedMy internet is T1 by Verizon. My mom's company Siemens pays for our internet because she works from home as medical tech support on the phone. Okay so the T1 had to be laid out to our house underground I think because where we live, other brands of internet aren't available. The T1 goes from the box outside into our basement and hooks up to a Cisco 1721 modem. From the 1721 the internet goes out to a wireless router that is sitting right next to it. This wireless router is a Linksys WRT160N V2. We have several cables coming out of the WRT160N V2 to go to the first floor for hardwired connections, but one cable goes to the attic and connects to a second wireless router. The second wireless router is a Linksys E2000. We have several cables coming out of the E2000 that go to the 2nd floor to serve as hardwired connections.Okay so let me explain where things went wrong.
After a storm our power went out. Eventually the power came back on, but every now and then our internet would shut off for like half a day then turn right back on, so our internet was getting really really spotty. The [b]AL[/b] light on the Cisco 1721 would come on every time the internet went out. It was so bad that my mom had to get an aircard from verizon to get internet. So after two weeks of spotty service and arguing with verizon trying to get them to come fix the problem, they said try resetting your wireless routers because they might have "bad data" in the lines causing spotty connection. So we reset the wireless routers by holding down the reset buttons on the back. Well.. this reset all of the settings for the routers which Cisco facilitated set up, and now our wireless routers are out of warranty date so they can't set the wireless routers back up. However, we have copies of the online wireless router set up page, so we thought maybe we could just set them up ourselves.Well the problem is... We don't know how to connect to the wireless setup pages.. I read something on the internet about setting up wireless networks and to type 192.168.1.1 into our browser(Mozilla Firefox) and that would bring us to the wireless setup page. But the page does NOT ever come up.
Another way to find the IP address of our wireless routers would be to try going to the cmd and typing in ipconfig and using the Default Gateway IP address for the browser to connect to the setup page but that doesn't work out either.... Right now I unhooked the Linksys WRT160N V2 and hardlined the Cisco 1721 to the Linksys E2000 to a PC on the second floor because I figured it wouldn't work out if we had two wireless routers running at the same time. Currently the browser is taking me no where at all. It just says "Connecting..." but nothing is loading up at all.I tried hardlining from the Cisco 1721 to my mom's laptop, which is her work computer, and I got no response at all. I figured it might just be her work computer that was messing up and not allowing her to hardline into the 1721 so I tried hardlining the Cisco 1721 straight to the PC desktop on the second floor(we have no other laptops other than my mom's work laptop) and nothing went through. Then my dad says the Cisco 1721 has been configured so it doesn't direct connect, meaning that it has to go through a wireless router.
I am using a bunch of Cisco 1721 routers for my T1 lines. We recently purchased Digi cell modems as a backup for the T1. On configuring vrrp to work on both devices I discovered that IOS 12.3(6c) does not support the "vrrp track" feature. After reviewing the Cisco Feature Navigator I could not see an IOS that will support the vrrp object tracking. Is that correct? The routers have T1 WIC's installed. If it does work what is the latest IOS that will work on this end of life product?

The router has a full BGP routing table learned via an upstream (EBGP) peer neighbor, and an IBGP peer. The CPU utilisation seems fine, as is memory usage. CEF seems to be running okay.

I have been trying to understand from a long time about the throughput capacities of variety of Cisco Routers and Switches. Have searched over a million pages on cisco.com for data sheets/documents/etc. but havent succesfully got a single document highlighting all of what i need.
I have got queries on the below issues:Which model of Router can support upto 2Gig's of WAN Internet connection running BGP? Any list of routers and switches supporting variety of throughput's from 1 MB to 1 GB.I have heard some experts stating "Switches don't have throughput concerns as they switch the traffic and don't need to route traffic" How true is the statement?? and if it is, Why do we require 6500's instead of 3560 Distribution Switches.
Can LMS 4.1 give a report for port capacity in stack switches? We are starting to have issues where our techs are going out and plugging devices into switches and the switches are getting full. We would like to be able to see how many ports are left in each switch.
