Redundant Router Internal Connections

Hi,
I have a setup where we have one internet router. Internally, the router is connected to two Firewalls operating in an active-passive scinareo.
Currently we are using a WAN switch with VLANs to establish a connection to each firewall.
We need to eliminate this WAN switch as it is a single point of faliure. Is it possible to create a l3 etherchannel from one side (Router side)?
*For the passive firewall all interfaces will be down and will only comp up when the first firewall is down.

Rami
Sincere apologies, i understand what you mean. I was being a bit stupid (a not uncommon occurence ) and probably managed to confuse you as well. My fault entirely.
For some reason i was thinking of two routers and of course the problem with one router is that two ethernet interfaces cannot be in the same IP subnet. So you could either -
1) use a bridge group on the router to bridge the two interfaces together and assign the IP to the BVI. One of the links would be blocked by STP.
or
2) use stackable switches as you say so you can spread the etherchannel across the stack members
I haven't used the BVI solution in a production network but it should work if you decide you want to go that way.
The advantage of the switches is that both uplinks to the router would be active and forwarding so you get more throughput but this may or may not be a concern for you.

Trouble with VPN and Verizon MI424WR router - not connecting to company intranet

I need to connect to my work intranet and via VPN. There was no problem accessing both when I had Verizon DSL. Since I switched to FIOS, I can access email via VPN but not my Company's internet and various internal company websites. I saw a previous forum with a similar problem using the Actiontec router, but wanted to make sure I tried a correct fix for my router. My router is connected via both Coax ad Ethernet to the ONT since I signed up for FIOS internet first and then added TV later. I don't know if both are active. I have a spare Linksys wireless G router I can add to the network if needed. My router firmware is 20.10.7.
Solved!
Go to Solution.

Thanks to all for the suggestions. I could not see how the VPN software was the culprit since it worked at various hotels, Panera bread ... but decided to try to uninstall and re-install the latest version. Viola, I am now working. I plan to leave the linksys router in the system since the speed is significantly faster.

Having issues configuring DHCP and with Redundant router

Hello everyone
I am new to Cisco and I am having few problems in configuring my topology in Packet tracer.
I am having redundancy in router and swithes both,
I have assigned one layer2 2960 switch as a VTP server and asssigned VLANs from that switch then assigned ports to the hosts in access layer switches.
Problem 1: If I take my Router1 off I am unable to ping so the pupose of having redundant router does not serve the pupose.
Problem 2 : I need to assign DHCP server for the users who will be connecting wirelessly with Access Points, so can I configure DHCP on Access Points which I am unable to do so in Packet tracer any idea how? / Or shall I configure the DHCP on Router1 and Router2 and exclude the addresses I have assigned to all the hosts connected using ethernet.
Also how can I configure Email server in this tolpolgy and where?
Thank you
A.K

Hi Asif, Jeff is right.
(1) You need to configure either HSRP (Hot standby routing protocol) or VRRP (Wirtual routing redundancy protocol), or GLBP (Gateway load balancing protocol).
With either of this config, you will be able to configure 1 logical IP address, which will act as a gateway on your computers. However, both routers will need different IP's (all within the same subnet). You will also need to create multiple HSRP groups to support all your VLAN's. So one HSRP group per VLAN. The logical IP in the HSRP group will act as the default gateway on computers within the VLAN.
Though I don't think packet tracer supports any of the above configs - FYI it's part of the CCNP Switch sylabus. So the above explaination will make sense after you've got a good understanding of HSRP, VRRP and/or GLBP.
(2) I would recommend setting both the Router as a DHCP server, and configure the Access Point (AP) with a static IP (disable NAT and DHCP on the AP)
(3) In packet tracer, choose the Server icon and check it's properties. You should find an option to enable EMAIL server. Connect it to any of the Distribution layer switches.
Hope this helps get you started on the learning curve :-)

If the wifi on my iPod Touch is on nothing else on the router will connect to the internet

Ever since I updated my iPod Touch 4th Gen to iOS 6, If the wifi on my iPod Touch is on nothing else on the router will connect to the internet..
It's the weirdest thing.
My Wired and WiFi computers are experiencing DNS errors, unresolved URLs and in general having difficulty connecting to the internet...
That is.... UNTIL I SHUT OFF THE WIFI ON MYiPOD 4th Gen TOUCH!!!
Then everything works fine.
I've reset my router, several times.
I've reset my Cable Moden, several times.
The problem persists until I disable the WiFi on my iPod

Try the following:
- A reset. Nothing is lost
Reset iPod touch: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Restore from backup
- Restore to factory settings/new iPod.

Issue with 2wire dsl router when connecting power pc g4 via ethernet

Issue with 2wire dsl router when connecting power pc g4 via ethernet. The 2wire will keep resetting. When I connect my macbook pro via ethernet to the 2wire all is ok, but as soon as i connect the power pc. . . .reset. I have emailed 2wire support. They recommended using a different patch cable. Tried that.. .. anyone else having this issue???? Any help would be appreciated. . .

Search the discussions for issues with 2wire dsl routers. This has come up before in a discussion I've been involved with, but probably not to do with the MDD. I do remember it being a design issue with the router, something that was done to it before dispatch.
Let us know if you can't find it and we'll have a look.
If you afford it, bin the 2wire and go buy something decent like a Netgear.

As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule, or do we need their router to connect to the time capsule?

As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule or do we need the Verizon router to connect to time capsule?

The Time Capsule is indeed a wireless router with simultaneous dual band capability...and a hard drive for backup purposes. You can use that to your advantage if you configure the Time Capsule as I suggested in Bridge Mode.
The Time Capsule will provide a 802.11n 5 GHz band and a 802.11n/g/b compatible 2.4 GHz band to allow virtually any device to connect to the network.
I suppose that you could also use the "g" wireless network provided by the Verizon router as a "guest" network or something similar if you really do need another wireless network.
It might be possible to configure the Time Capsule as the main router on the network....that's a question for Verizon. But even if you might be able to do this, I'm sure it is not supported by Verizon, so you would be on your own in the event of any Internet connection difficulties on your service.
And, since the Time Capsule does not have a built in modem....you would still need to add a separate modem to the installation anyway.
That's why my suggestion is to use the Verizon device as the "modem" and let the Time Capsule provide the dual band wireless network and of course, handle the Time Machine backups.

I just purchased an Apple TV. I have a pc running windows 7. It is connected to a router and the router is connected to a wireless router. I connect my iPhone, iPad and apple tv to wireless network but do not know how to put the pc on the wifi network

I just purchased an Apple TV. I have a pc running windows 7. It is connected to a router and the router is connected to a wireless router. I connect my iPhone, iPad and apple tv to wireless network but do not know how to put the pc on the wifi network so the Apple TV can do home share.

I don't mean to be facetious but sometimes the simplest things are overlooked. To connect to your library you have to have the computer where the iTunes library is located running and with iTunes open. It also needs to be on the same network. My network is dual band and works with either stream but a friend of mine does not. He has to set the computer and the Apple TV to the same band. Hope this helps.

HELP I have a wireless Linksys router WRT54G connected th...

HELP I have a wireless Linksys router WRT54G connected through my cable company broadband modem on a Mac. I have another computer to which I installed wireless capability because it didn't come with it. This required attching some piece of equipment to the back of the PC which enabled it to get on the internet without another cable modem. My question is this. If I get an iphone or a laptop(with built in wireless ability) will I automatically be able to go on the web because of the router on the Mac.

yes certainly... if you get any wireless device in network that would certainly connects to a wireless n/w of router...

I can't get my router to connect. Someone pls help me.

I've been trying for like 6 hours to get my router to work. It's recognised but it can't connect to the internet it did yesterday but now it won't. Also I've been trying to find my network key and the blank username and admin for password doesnt work. The model of my router is a WRT54GS.

1st reset the router back to it's default settings by pressing the reset button at the back of the router for 20-30 seconds. Then unplug the power of the router for 10 seconds and plug it back in.
Then to reconfigure the router from scratch including setting up your wireless settings... I recommend using a fairly easy to use software called EasyLink Connect. You can download this off the internet (by bypassing the router and connecting to the modem) from this website: www.linksys.com/easy

Is it possible to create internal connection in SM59

Is it possible to create internal connection in SM59? I tried but it seems it is not possible.
What are internal connections made for?

Internal connections is basically the connection between you CI and you DI's and viceversa... this connections are automatically generated when the instaces are installed.
I wonder why you want to set one up manually.

Router Wont connect my Xbox 360

Hey, I have a Cisco E2000 and I have multiple devises that work but not my xbox 360.
I have
2 computers
2 iphone 4s
2 ipods
iphone 3gs
They all connect to the internet fine. My Xbox 360 never connected.
the xbox can connect to the router. Then the router cannot connect to the internet.
Please help me!

You mentioned that the xbox can connect to the router. Is it connected wirelessly to the network or wired to the router? What excatly do you mean it won't connect? You are unable to connect to the network or to the internet? Is your concern with NAT? If it is already connected to the network then there is no problem with the router (as what you have posted other devices are working, it shows that router is working fine). You might need to forward ports in order for you to use or connect to xbox live. And if it still won't work with the router, connect your xbox directly to the modem and test your connection. If still not working, contact your service provider. But try the ports first.

Monitoring of topLink internal connections pool

we wish to monitoring use of Toplink internal connections pool : numbers maximum used, a minimum number used.
we know to do it with the external pool (OracleAS) but not with the internal pool.
Regards

The only way to get this information is through API calls. If you have a Server (oracle.toplink.threetier) you can ask the read and default (write) connection pools.
        // Display Read Connection pool info
        System.out.println("READ Available: " +
                           server.getReadConnectionPool().getConnectionsAvailable().size());
        System.out.println("READ Minimum: " +
                           server.getReadConnectionPool().getMinNumberOfConnections());
        System.out.println("READ Maximum: " +
                           server.getReadConnectionPool().getMaxNumberOfConnections());
        // Display Write Connection pool info
        System.out.println("WRITE Available: " +
                           server.getDefaultConnectionPool().getConnectionsAvailable().size());
        System.out.println("WRITE Minimum: " +
                           server.getDefaultConnectionPool().getMinNumberOfConnections());
        System.out.println("WRITE Maximum: " +
                           server.getDefaultConnectionPool().getMaxNumberOfConnections());Doug

The device need to be very close to the router to connect to the network otherwise it disconnects when it is far little bit

Router drops connection

Hi, I have a WRT300N that acts as a router/DHCP in a small home network. I have a p2p program, DC++, which requires port forwarding to work correctly. I have setup this in the router, port 1412 and the computer ip address to forward to. The problem is that the router drops connection to internet now and then, with 1-2 hrs. intervals which disconnects all hubs and downloads/uploads in DC++. Very annoying indeed. This has never happened with previous routers including a 3com and a Zyxel, so it has to be something with the WRT300N. What can cause this? I'm not sure what information to send with this message, so it's better if you tell me what you need. Thanks in advance, Mattias Sarling

hi... try upgrading latest firmware on the router, go to www.linksys.com/download and download the latest firmware for the router, after upgrading firmware on the router, reset the router back to factory default settings and reconfigure it according to ISP settings, reduce MTU to 1458, try reducing connection on p2p program... also you can enable QoS to manage bandwidth.

WRT54GS Router-trouble connecting to vista computer

I have 2 laptops. One is xp and one is vista. I used the setup cd to install my new router on both of them. the first thing i noticed was that there were 2 very different setups for the vista and the xp computers. when i loaded it into the xp computer it came with a proram called "easylink advisor". All i did was folow the directions and it was perfect, the xp computer is wireless. when i go onto the easy link advisor it has an option and tells you how to connect another computer to your router wirelessly. I followed all the steps on that and it did not work. as soon as i unplug the blue cord from the vista computer the internet connection is lost. I noticed that the router is connected to that computer becasue when i go to "manage wireless networks" it is there, but when i click on the symbol by the clock and click "connect to a network" there should be a lst of all the networks i am connected to and there is nothing there. so where is my netowork??? its there according to the "manage wireless networks" page!?!?!?!
I hope that someone can help me with this problem. I have been at this all day!
thanks

Try turning your ON the wireless switch of the laptop & you will be able to see the wireless networks...click yours...click CONNECT...if secured it will ask you for hte wireless password & you will be able to go ONLINE WIRELESSLY!!!!!!!!!!!!!!!
