Cisco WAN :: 1800 / 2800 / 2900 - Using ADSL As Backup Line

Aug 1, 2011

Site A, site B, site C, site D is connected using leased line each other. We are using Cisco 1800, 2800 and 2900. Each site also have Internet connection using ADSL connected to firewall, we are using pix 501 and ASA 5510.My question is, can i use the existing ADSL line to be use as a backup line if the leased line is down on any of the site??And i want it to trigger itself, once the leased line is down, the firewall UP the backup line? something like that..

Cisco WAN :: 877 / 2800 - Use Static ADSL As Backup Connection

May 3, 2011

We have a few WAN connecting sites to ISP using BGP. we are looking at getting backup link for 1 site.

We have decide to use an IP WAN ADS L link. we will have 877 and 2800 for each link. from understanding, we have a static routing on IPWAN service. means when both BGP WAN and IP WAN connected to the ISP. ISP will use ADSL as primary ignore the BGP link. so other sites will see a BGP route coming from ISP via the ADSL link for this location.
 
So we have find a manuel solution, leave ADSL unplugged of power but setup same LAN ip address and connect the cable towards the core switch. when WAN link fail, switch on ADSL. So the static route will advertise to the rest of sites. 
 
just want to know is there any auto solution can disable the ADSL link/ ppp link when the 2800/WAN route is up. and enable the ADSL port when the WAN is down. not sure if HSRP/backup interface/tracking will work? and how?
 
site office switch - > 2800  - >  ISP  - > ADSL ->  ISP 
(need this link to be backup and protocol down, so the ISP will not able to connect to this link and advertise as next hop)

Cisco WAN :: Configuring QOS Between 2800 And 1800 Series Routers

Feb 20, 2012

We have an MPLS network to a half dozen remote sites.  At our main location we have a 2800 series router.  In the routers config are the following lines for QOS.  When I go to the routers on the other end of the MPLS, none of them are configured with these same policies.  Would these not be in the running config of the 1800 series routers, or is this not setup correct and this should be removed?

Cisco WAN :: Failover On Router 1800 Having DSL And Leased Line

Feb 4, 2013

Leased line is between dammam      to dubai and the dammam office is getting internet from dubai.The ip address of Dammam      office is class A (Public IP) x.x.x.x and for dubai it is y.y.y.y which we are      using as proxy for accessing internet.I purchase the local DSL      direct line connection through cable from Local Provider and this ip address range is      192.168.1.0 - 192.168.1.254.Is it possible to use the DSL      line as failover, so if one line goes down the user should remove proxy      and can use local internet.The router which is using is      cisco 1800. 

I believe that failover is possible, 100%, but would like to know how I can do it and requesting for sharing more inputs about failover in this case.

Cisco WAN :: Configure Backup Links On 2800?

Oct 16, 2011

I currently admin a WAN link between two international sites.  I have a 2800 at each end. The primary connection between the two sites is 20MB Ethernet PIP MPLS BGP circuit.  I also have a pair of T1's in a PPP multilink that I switch over to in the event the primary circuit goes down.  I currently am doing the switch over manually.  It takes me about 15 minutes to complete it, but I know there must be a way to make this an automatic process.
 
So a couple questions:
 
1) Is there a way to create an "enhanced multilink" with the 2 T1's and the Ethernet circuit in the same bundle, in effect giving me 23MBps bandwidth while still being able to maintain connectivity if one of the 3 links goes down?  This is my preferred solution
 
and if 1 is not possible then
 
2) Is there a way to configure the router so if the Ethernet circuit goes down, all traffic will be automatically directed over the T1's, and then come back to the Ethernet when it's back online?

Cisco WAN :: 876 To Use It As Backup Line

May 5, 2011

One of my branch offices is connected to an ADSL line as well as a VDSL line.Since I really don't need the ADSL line I came up with the idea to use it as a backup line.So I searched google and found this nice little article URL. I wonder if the router will switch back to the primary ISP if the primary line comes up again?

Cisco WAN :: Reliable Static Routing Backup Using Object Tracking On 2800

Jan 29, 2012

I was configuring route tracking at a client with several sites to route across GRE tunnels and being able to detect a failure of the main site. To my surprise when configuring a 2800 series router (after sucessfully configuring a 1800 series on the same infrastructure), a 2821 with  IOS 12.4(24)T2 IPbase, the commands for ip sla object tracking don't show up.The feature navigator says the router supports this, but it just won't take the commands (also tried older versions of the commands such as "ip sla monitor.." and "rtr .." to no avail).

Cisco Switching/Routing :: 2800 Series - Dual ADSL Links?

Jan 31, 2012

In a site we currently have 1 BT provided ADSL link which is currently terminated using their device which I believe is some kind of 2wire device, which is extremely slow due to distance from the Exchange (4Mbps)...We have a growing number of users here and want to install a second ADSL line from BT to give them increased performance.
 
We have a Cisco 2800 sat not doing much so I was wondering if I could use this to load balance the link? I know BT do not support MPPP so therefore the maximum any user can get will be the speed of a single link (4Mbps)...But basically how can this be done..
 
Can I leave the two BT routers in place and place the Cisco 2800 behind them, or do I need to purchase two ADSL modules for the 2800 and terminate the connection there?Also once done, what do I need to do regarding actually setting up the load balancing? I have seen this:
 
[URL]
 
But am unsure as to how relevant it is? I am not sure I understand what the ACL's are being used for? I just want all users on the LAN to load balance out...
 
Also I am unsure of this statement:You potentially need to add policy-based routing for specific traffic to ensure that it always uses one ISP connection. Examples of traffic that require this behavior include IPSec VPN clients, VoIP handsets, and any other traffic that use only one of the ISP-connection options to prefer the same IP address, higher speed, or lower latency on the connection.I do not understand why a established session such as a VPN client, would ever traverse the second ISP connection anyway?

Cisco WAN :: 877 - ADSL Line Drops

The "no retrain. sleep 20 seconds" messages continue forever more until somebody power-cycles the router - which is a bit inconvenient as two are 300 miles away. Surprisingly, our event manager applet isn't triggering the reload either, which defeats the object.

Broadband :: Connect 2 ADSL Routers On 1 BT Line?

Feb 19, 2011

Our church has 1 phone line, we run BTBusiness Broadband at one of the building where we have a couple of charities based. We have the phone line connected to an extension at the other end (where the Church is) >80m away. Any way of running a second concurrent router on the extension so I can set up an office with a VOIP number, pC's printers etc there too? We use Devolo ethernet over mains and wireless for the main building, but the church itself is on a completely seperate mains power supply so I can't use that. I could run 100m Cat 5 and locate a switch on that, but any way of achieving something similar over the phone cable which is already in place.

E1000 - Use ADSL Line With Broadband Router?

Aug 16, 2012

I have a broadband router (Linksys E1000) which I've flashed with a DD-WRT firmware. After doing so I realized that this router doesn't have an interface for ADSL port(RJ-11). How can I use the Linksys E1000 for my home network?

I've heard that I can use ADSL modem(not a router) & plug the RJ-11 to it & take from it the Ethernet & plug it back to the E1000(in the WAN port) would that mean that I can get just a modem and not a hybrid?

Note: Also, I have to mention that my ISP is using PPPoA & DD-WRT is not supporting it, but i googled & they said that the ADSL modem cab be the rescue. Can I pick any ADSL modem for this specific scenario or am I looking at a specific model?

Secondly, can I use my old router to do the job instead of buying a new ADSL modem ? & is it a good approach ? or should i buy a new ADSL modem ?

Update i turned my DD-WRT router(E1000) to act as access point, since this is the only way that i can use it with the DD-WRT feature. & i think this is better than have nothing :) I can now have the DD-WRT functions ;)

Cisco Switching/Routing :: 877W ADSL Line Interface Not Initializing?

Jan 19, 2012

Is the ADSL line interface on Cisco 877W not initialising a known issue? This interface on my router has been in this state for more than one month, with the rest of the router seemingly operational. The interface was connected directly to my ADSL broadband and worked well for two years. But then, about a month ago, the interface went down. I saw the exact moment this happened recorded as a syslog message. The only information was that the interface status had changed to down.
 
Initially I thought this was a matter of reload the router and all will be well. Did not happen. Then I thought my broadband connection was to blame. However, this option was quickly ruled out. So I went on to exhaust all troubleshooting options, including reflashing the router with the saved image and totally changing the configuration. Still no change. I have had to go back to my old BT home hub for internet access. In terms of speed this actually works a lot better than the Cisco router. But I would still rather have the router connected to my broadband line. What can I do to bring the ADSL interface back to life?

Cisco WAN :: Dial Backup To ADSL Service Using 877 / External Analogue Modem

Jan 4, 2011

I'm trying to get a solution together for a dial backup to an ADSL service, using an Analogue modem.The kit list is as follows:

Cisco 877
 
Multitech MT5656ZDX External Analogue Modem or USR 5630D External Analogue Modem
 
Rolled patch cable RJ45 to DB25M adapter (pinout from a cisco guide)
 
So far I am unable to get the router/modem to dial out at all. I know the modems work, I have tested them from Windows.
 
I have attached a couple of outputs from "show line" and "show line 1" from the router and also what I think are the relevent lines of config although it will be too much config and probably jumbled by now as I've tried quite a few things to try and get this working.
 
I am more concerned with the config relating to the connection of the analogue modem than the routing element.

Cisco WAN :: Poor Performance / Packet Loss With 887VA Router On ADSL Line

Dec 6, 2012

We have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
 
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?

Cisco Switching/Routing :: 887 Router / 1841 - Dial Up On ADSL Line To New Site

Nov 9, 2012

I've moved a Cisco 887 router from a site where it was used to dial up on an ADSL line to a new site where we have a EFM circuit which terminates at a Cisco 1841 router managed by our ISP. I therefore need to re-configure our 887 router to work as a conduit from our servers back to the Cisco 1841 as its gateway.
 
I have asked from our ISP and they told me that i need to configure the 887 to use IP address 176.35.140.65 255.255.255.248 and its gateway should be 176.35.140.70. That's great advice in theory but I don't know how to configure this correctly
 
Our internal network is using subnet 192.168.42.XX which will need to be retained for local devices.
