i am using cisco 2821 router at the edge in my network where the WAN link is terminated.i want to configure Redundancy . So will 2821 support ? If yes what is the another router .Is it the same series or different for redundant configuration.
View 2 RepliesWe are setting up a disaster recovery site which will host redundant copies of our servers and critical data in Kansas City. In the case of a disaster, our headquarters site would be totally gone.
Currently we have 7 branch offices that communicate to our HQ via VPN tunnels (either over an Internet circuit, or over a Cox Communications Ethernet WAN circuit). The branch sites each have a 2821 Cisco ISR Router. At the headquarters and at the DR site, we use a Cisco ASA 5510 to terminate the VPN tunnels and do all of our backbone routing. Routing on the ASA and on the branch routers is all static, using a routing protocol would be a nice upgrade in the future..? We use lan-2-lan IPSEC VPN tunnels, no GRE/VPN is in use because the ASA does not terminate it. What is the best way to setup my branch routers to automatically or manually fail-over to connect to a different ASA at the DR site?
Also, if my Headquarters site is still up, but either my Internet circuit or the Cox ethernet circuit at the headquarters goes down. How can I re-route all traffic in a loop back to the headquarters over the one good remaining circuit?
Is there a better way to do what I want to accomplish? BGP is not an option at this point due to its complexity.
I have two 5505 ASA. I would like to know can I make two 5505 failover redundant with active standby setup?

We would like to add another Nexus5k to this topology. However, it has to be a zero downtime infrastructure add-on. When setting up the keep-alive, peer-link, vPC and vdc domain, will there be any upset in network traffic on the current N5k?Also, are the Nexus5k configurations synchronized or are they independent from one another? Before setting up the new 5k, should i configure it to teh 6509's, and vPC's to the Nexus2k's before setting up peer-link?
We are setting up an old office building as an offsite data center. The network cosists on a PIX 501 firewall and a 2811 router. I am attempting to setup a GRE tunnel over IPsec back to the main office. The main office consists of a PIX515, a 2821 router, and a 2921 router.
There is also an ASA5510 in our main office that is used as our primary connection for all of our external services and as a GRE endpoint for our other offices. The PIX515 is used to connect our main office clients to the internet and we would like traffic between it and our offsite data center to go across it as well. The default route is to use the ASA. We used policy based routing on the 2821 and 2921 routers to direct the appropriate traffic to the PIX515. Right now I am not able to get the tunnel setup. It appears that the offsite datacenter is sending packets but is not receiving any when I issue the “show crypto ipsec sa” commands on both firewalls. I will show the output of that command below.
Main Office The external address 198.40.227.50. The loopback address 10.254.10.6 The tunnel address 10.2.60.1

Can someone give me a sample router config (Cisco801) for the below scenario. Not familiar with networking.Server with 2 nic, connected to 2 different switches, each switch connected two lan interfaces of Same cisco801 for redundancy.Server must be able to reach gateway IP (in router) in case of either switch failure/server NIC failure.I also have 2 vlans, going to use same link for management vlan and application vlan.

The Router that I have is 2811 where it contains two Fa ports only, so I put an access switch between the two ISPs and the Fa0/0 then configured the Interface Fa0/0 with two IPs ISP1 and ISP2 as a secondary.
The problem that I faced that when ISP1 become down the another secondary IP (ISP2) stay down and the internal users have no access to the internet.

I have a cisco 2821 router and it has an advanceip image in the flash each time on reboot it gives the message software forced crash and checksum error and finally goes into rommon. i tried xmodem and tftpdnld -r but same problem persists. I even changed the CF with a working router's flash but the same problem occurs.I also loaded an ip base image of about 13Mb size and all the same problem repeats with it.

View 1 Replies View RelatedWe are using a 2821 Router as our boundary router. It has installed into it a 9 port HWIC for layer 2 switching as well as allowing the router to communicate on the Network Management VLAN. All of the devices on the Network Management VLAN are segregated from the managed traffic, which unfortunately also doesn't allow them external NTP services. Can the router be programmed as a NTP server so that all of the network appliances can utilize it for NTP from either it's NM Vlan IP address or from a loopback address?

- voice calls
- ospf
The ospf is not the cause of the high cpu , because the high cpu utilization appears before I put the ospf proccess on the router.

View 2 Replies View RelatedI'm using a Cisco 2821 router to provide temporary Internet access for a private network of about 300 users for a conference at a hotel. The hotel has provided me a public IP address for the WAN side. On the LAN side I have a 10.x.x.x /8 subnet with the router providing DHCP and NATing (overload) across the WAN interface.
Users can pick up an IP address and access the web. Light web pages such as Google tend to load without issue, however if a user does something that takes more time, such as streaming a Youtube trailer or opening an RDP session, the connection will freeze.
It doesn't appear to be related to bandwidth availability. Pings return on average 10-15 ms. However, I will get a request time out about every 10th continual ping. Steaming video will load about 4-6 seconds worth of data, then will appear to freeze without dropping. Doing something like speedtest.net will send a large amount of data then will hang, without ever ending the conversation.
This doesn't happen when I plug a laptop directly into the hotel public Internet line. They also don't have issues with their network similar to this.
I do not have any ACLs, etc. loaded. The router is basically wide open as far as I can tell. I don't see the router resources getting used much at all.
Recently I have bought a 2821 router from an auction. The router did have some configuration and password on it. I tried to break into it by restating it and pressing control and pause break signal. Old cisco method. Now when I try this method on my 2821. It does say that password recovery is disabled on the router. After this message router proceed with normal boot process. How to break the password ? Even if I loose the configuration.

Currently I'm looking for a way to failover our internet connection from one site to another site over our MPLS line, should that internet connection go down.

I am sitting on Internet and want to copy IOS Image to router. I can SCP, itu authenticated to Router but ends with a message "host is not communicating for more than 15 seconds".
Router : Cisco 2821
Current IOS: (C2800NM-ADVENTERPRISEK9-M), Version 12.4(24)T1.
I am looking to find the correct router for a 50 Mbps Ethernet connectin that is for Internet traffic. It will need to support 50 Mbps throughput, along with routing protocols for BGP, and maybe NAT/ACL's. It most likely will be a used router, in the 2800 series. I'm thinking a 2821 would work, but need to make sure before I pass it on to the customer. They currently have a 3660 they were thinking of using, but I think it would be too weak, and probably only pas 30Mbps at the most before it chokes. They are a mini ISP with their own ASN, Tier 3.

Now I want to upgrade the IOS to version 15 to get a CME version 8.6 but I faced a problem that the flash of the 2821 is 64MB and the IOS version 15 required flash 128MB. I tried to replace this flash with another 128MB installed on Cisco 2811 router but when I installed the 128MB flash on the 2821 CME the 2821 didn't boot from it.

IOS running on that device is c2800nm-adverterprisek9-mz.150-1.M7.bin . Once you have ZBF config you cant configure url-filtering using classic way ( ip inspect ) and this has to be done using class , policy maps .For this to to happen it is required to have match protocol http command under the class map , it wont work using the match access-group command.[code]
Once I put match protocol http command browsing becomes dead slow , also without using match protocol command I cant continue to configure Url Filtering . Is this a problem related to IOS where match protocol command isnt working fine . I have checked CPU utlization of Router and it was roughly near 7 percent .
I am looking for a simple router recomendation for multihoming dual 100Mbps internet connections with BGP routing. What are the current best practices regarding required resources for the full Internet BGP routing table? We were thinking of specing a 3945 for this application, but is that overkill? The customer has a 2821 that is not in use, I'm thinking this would be too slow for Internet BGP routing combined with the 100Mbps line speed.

I then have a cable modem connection going into the gigabit Ethernet GE 0/1 port on the router.
Right now, the cable modem provides a backup connection in case the T1s go down.

View 3 Replies View RelatedBasically I run 3 voice gateways on 2821 routers. In two of my routers I've had fan failures, one router has had two fans die and one has had just the one.
I was going to buy the offical Cisco fan replacement kit but then I thought with such as high failure rate I'd rather buy something else and better guarentee the service to my call centres.
So, what i'm asking is:
- Is there any reason why I cannot procure a standard 80mm 12V fan with a better rating (cooling and reliability) and install this in my 2821's?
I understand this may invalidate any warranties but mine have long expired.
I've 3 interfaces on router:
Gb0/0-ISP01 with DHCP client
Gb0/1-ISP02 Static IP 192.168.2.x/24
Fa0/0 - LAN 192.168.1.1/24
I want to know, how to configure:1. Set the IP of interface Gb0/0 as dhcp client from ISP01 and make it as default route.
2. How to configure the ip nat.....overload?
3. How to use the ip sla to monitor internet connectivity to 8.8.8.8 for ISP01, if it fails, to go to ISP02.
We've got Cisco 2821 for our 90mb/s Internet Access. Its CPU usage is around 80%. Show process cpu does not show any cpu proccess with high utilization. But we have got plenty of policing configured for our clients using policy maps. Can this policing affect cpu usage?
