Cisco WAN :: 2921 Configuration And ATM Circuit?
Jun 4, 2012
We recently purchased a Cisco 2921 router to be our edge device for a small satellite office (24 users). In addition, to the router we purchased a vwic3-2mft-t1/e1 module. Now the surprise, we ordered a bonded T1, I thought we were getting frame-relay circuits from Verizon, but someone ordered a 3M IMA circuit. I am new to configuring serial connections, and had planned out a frame-relay configuration. With that said, I have the following questions:
1. Can I setup a working serial connection to Verizon using the installed ATM circuit and the 2921 and vwic3-2mft-t1/e1 card I have? If not, what do I need in conjunction with the 2921?
2. With the frame-relay configuration, I enable controllers, configured the MFR interface and sub-interface, and serials. How much different is setting up serial ATM connections?

I have a question regarding Circuit-speed WAN performance. I purchased a 1Gbps Internet Link and want to know what my max through put would be on that router.
The Data Sheet states 35Mbps, why buy this router if I can not utilize this 1gig circuit.

I found that ADSL is packet switching type of communictaion. Definition for circuit switching is "A type of communications in which a dedicated channel (or circuit) is established for the duration of a transmission."In practical, telco line connects to the ADSL modem/router through which we are communicating to internet.In this context I have some doubt.The telco line which is connected to our ADSL modem is not shared with any other device ,connects only to the CO of the telco where we get the internet connection.That means the line which connects to the modem is dedicated upto CO.then it becomes circuit switching or not upto the CO.

Imagine you have 5 sites, one router each site (2851 as CE) connected to MPLS network. All sites have max 3xT1.Requirement:In case CE router or circuit to MPLS fails in any of those sites, I need to provide backup circuit to reach MPLS network.
Proposal:Bring one Internet circuit to each of those sites and create DMVPN to every site.
Question:Let's say Site1-MPLS circuit goes donwn.
Then all traffic from Site1-MPLS should flow thru the IPSec tunnel to all other MPLS sites. Am I right that the traffic coming from Site1-MPLS will ingress via the 2851 CE routers, correct? Is this the typical design? How to accomplish this, I'd like to setup a lab to simulate it.

if i plug a cisco 880 router in to a 100MB WAN Ethernet circuit what throughput will i get? on cisco site it says 25mb/sec but if it is Ethernet shouldn't it be done in hardware and get the full 100mb/sec?
I know that a 1841 plugged in to a 40MB WAN circuit can match that speed but Cisco site say it only can do E1 speed.

The only option that I have under the IOS that's installed on a 2900 series router is track. I don't have a version that supports SLA. The interface is connected to a switch that the ISP gave, and all of the tests that I've done refuse to make the circuit go down. If I were to lose the circuit, the interface won't show to be down unless the switch were to go down.
Is there any way with track to see that the provider's circuit went down on a switch? I was going to set up sla to ping the ISP's address, but I can't do that unless I upgrade the OS. These are a pair of routers running hsrp at a remote datacenter. Is sla the only way that I'm going to be able to accomplish this? I have tried track with different options in gns and all of them keep the CE's interface up and doesn't show it down. Watching a route in the table isn't feasible because I wouldn't want it to fail over because another site is having problems. Tracking the route doesn't work for connected routes either because the route itself doesn't leave the table as long as the interface is up.

I am setting up a T-1 circuit and the instructions for the WIC on the router request that I use a RJ48C cable. I do not have one. Can I get away using a normal RJ45 Cat5e cable?

We currently have 3* offices located in London, Reading and Oxford which have a (ISP) VPLS service to interconnect all sites.I am using RIPv2 for intersite routing between all offices. We plan on implementing a backup circuit at the Oxford office for resiliency.There are 2* Core 4500 Switches, Core 1 is uplinked to the Primary circuit and Core 2 will be uplinked to the Backup circuit.At the moment Core 2 learns all of its routes from Core 1.My question is, if the Primary circuit goes down, how do we get the Routing on the Core Switches to than point out of the backup circuit?

I need to make sure I have a router available to work with DS3 circuit on remote site. A remote field technician tells me there is a 3745 router with "HSSI" and external Adtran CSU/DSU available. Is that an indication this can work with DS-3 circuit?Which specific Adtran CSU/DSU do I need in order to make it work with DS3?

We have 4 switches C3560 running EIGRP. We have PBR in one of them in this way: [code]We have conneceted a dedicated circuit in FastEthernet0/23.
The question is: ¿what would happen if circuit fails but FastEthernet0/23 remains in connected state? 192.168.1.6 will be unavailable.PBR will maintain forwarding traffic to IP 192.168.1.6? This involve that this traffic will fail.

Last evening when I turned on lights a circuit breaker was triggered. I turned it back on and it didn't trigger again. I went to sleep but when I woke up this morning and turned on my pc I noticed that I couldn't get online. I checked my router and it was dead - no lights at all. I've tried unplugging it, letting it stay unplugged, hitting reset etc... but to no avail.Lighting and the electric outlets are behind separate circuit breakers, but the only explanation I can think of is that the triggering of the cb and my 825 dying are linked. Am l looking at a dead router or is it more likely that the power adapter got fried? I don't have a fluke at my place right now due to early packing in preparation to moving away in a couple of months time so I cannot test the output voltage of the adapter right now. . Where can I get a replacement power adapter if that happens to be the culprit?

I thought I saw a post/question in regards to "how to" configure a Broadband backup for a MPLS circuit.. What I am trying to do is use a cable/dsl/ broadband (secondary) connection as a backup to a MPLS circuit (primary). I have EIGRP and BGP configured on both the branch endpoint and the tunnel headend. The tunnel is used by the interface that connects to the secondary circuit. The branch location router is a 1841 and the "headend" tunnel router is a 3825. I am wondering about the configuration/syntax of a "weight" or static route that can be used to have data flow over the tunnel when the MPLS circuit goes down - and then switch back to the MPLS circuit when it comes back on line.

Installation of 2 x 4 Mbps MPLS circuit on primary router (CISCO 2951) and 1 x 8 Mbps Ethernet link on secondary router (Cisco 2951). We have successfully implement the primary router with 2 x 4 Mbps MPLS circuit. Site is having two computer room CR1 and CR2 and distance between both room is 200mts. CR1 is having primary core router and primary core switch where the service provider terminated the new MPLS circuit and we have done the successful implementation. CR2 is having Secondary core router and secondary core switch where we needs to have the termination of Ethernet link but service provider has delivered the Ethernet link on the CR1 which is incorrect DMARC Location.
Both the computer rooms are connected via optical copper can we use that copper to connect the circuit on CR2, as per my understanding we can use the optical fiber to connect the wind circuit on secondary router on CR2 by using the media connector.

Is it possible to run 802.1Q on a point to point Ethernet circuit between 2 Cisco ISR routers? I need to carry multiple VLANs across an ethernet WAN circuit but not sure if a Cisco router would let me do this. I can surely lab up but was looking for expert opinion on what's best aproach to carry multiple VLAN across the WAN ethernet. Plugging the circuit to a LAN switch is not an option since this is a managed WAN router.

Using a Cisco 2921 router with an RPS 2300, I came across a table in the 2900 Hardware Installation Guide that I can hardly believe: table 5-3 seems to tell me that in order to back up ONE 2921 with RPS power, I will need an RPS with TWO 750 Watt or TWO 1150 Watt power supplies. Is it really true that I need to throw at least 1500 Watts of backup power at a router that has a main power supply of approx 300 W?

I need a router to connect to our ISP by BGP and in a future to a second ISP. Our ISP is going to provide us about 300.000 route entries by BGP. So router 2921 would be enough??? or should i go to a higher model?We are going to have 100Mbps with this ISP and probably in 3 months we'll have to double it. Also we'll need IPv6 support.I saw router performance [URL]f and it's has 480.000 PPS and 245 Mbps but for 64 bytes lenght packages. If the packets are bigger the throughput should be best I suppose... 1500 bytes about 5,5 Gbps. In the case you consider the model is sufficient, the flash or RAM should be increased?

i have one interesting problem with local PBR on 2921 router. Here is the case,On HQ site there is 2921 router with two directly connected ISP, and there is Branch which is connected to only one ISP. The configuration should be to connect HQ router to Branch router with two VTI tunnels, so that each tunnel on HQ site should be terminated on different ISP, and EIGRP will be monitoring each VTI status.The problem is on HQ site, there is only one way to specify router with LOCAL PBR configuration, so router should send on ISP1 terminated tunnel traffic to ISP1, and on ISP2 interface terminated tunnel traffic to ISP2.
As I know this configuratino should work, but I could't make it work on c2900-universalk9-mz.SPA.151-4.M4.bin IOS, and on c2900-universalk9-mz.SPA.152-2.T1.bin.
Here is simple config:
ISP1 ip is 1.1.1.1
ISP2 ip is 2.2.2.2
3.3.3.3 is Branch ip address.
!
ip vrf BRANCH
[code]....
when I configure one default static route, it starts workig, but both tunnels go with specified ISP, and also there is no vrf problem,when there is no any vrf config it also don't work. gre tunnels also dont work.

why Cisco 2921 Gigaethernet 0/1 is not coming up ? I also tried to connect the interface to another SWITCH with no joy.
ME3400 (ISP's switch)<-------------MPLS link--------------> Cisco 2921 Gi0/1 >>>>>>>>>>Port not coming up
I tried connection between ME3400 (ISP's switch) and spare switch and the INTERFACE of spare switch was in UP/UP state .Troubleshooting I did so far on Interface Gi0/1
1> Changed ths speed/duplex manually and revert it back to auto
2>diable keepalive
3> Tried differnet LAN cable with no luck
4> Please see HIGHLIGHTED part (in red colour) of "Show controller Gi0/1" command
I am pasting some of the SHOW command output R2921_MMP#sh run int gi0/1Building configuration.[code]

I have a 2921 on Ethernet MPLS circuit. Problem is Voice has jitter at 60ms and no dropped packets from source to destination. How to reduce the jitter? Is the polices correct using Cisco recommended Nb = CAR x (1/8) x 1.5?
The PE is honoring the DSCP marked packets.

I am trying to set up a new router for training.I am attempting to my First BGP multihome.
The router is a 2921.We have a bonded t1 line and a metro ethernet connection
we have 2 /24 networks 1 /23 and 1 ipv6 /48 ,Behind the cisco router we have 3 Open BSD firewall Pairs, that are used to segment the networks into the production, development and my lab.
one of the /24 and the ipv6 block are veriably subneted, these are the routes that I am having troubles with.I am attempting to aggregrate the /24 and the ipv6 block to go out to the internet.
they show up in the routing table as advertised but you can not reach any hosts through the cisco router.
here is the bgp config
address-family ipv4
network 24.104.xxx.240 mask 255.255.255.240
network 204.17.xxx.0 mask 255.255.254.0
network 204.138.xxx.0
