Cisco WAN :: How To Do IPL Connection Using 2801 Router To 1841
Dec 26, 2012
I need some clarification if it is possible to do an IPL connection between Cisco 2801 (T1) to Cisco 1841 (E1) via Ethernet (2801) to Serial (1841).
I am unable to find any documentation about this and I need to connect our network to our overseas office.
Our side uses the 1841 router and our provider has set-up our E1 connection to be via Serial interface while on our overseas office uses the 2801 and will connect via the T1 card, which by the way does not have any serial interface ports just ethernets.
So far checking on how to configure this, I am unsure on how the connection will happen since the info that I got is that T1 does not have the option to hold an IP address (also unsure on this though). With this in mind and that the 2801 does not have serial interfaces, does that mean that IPL connection would be via the available Ethernet ports?

I've been looking and I can really find much info about this, I got a 1841 and 2801 router with ADSL WIC cards and both are synching really low compared to my cheap home router
This leads me to believe I need a firmware update so I got the adsl_alc_20190.bin and loaded it into flash and reloaded my router but its still saying my firmware is using an embedded one.
sh flash:-#- --length-- -----date/time------ path1 1000636 Oct 4 2011 05:59:54 +00:00 adsl_alc_20190.bin

Currently we have a cisco router 2801 for Wireless Internet connection. And we are going to have another ISP that can provide us Fibre Optic internet connection rather than wireless.My question is that can we use this router for fibre optic internet connection? how do we go about this? what is the maximum bandwidth that the router can support?

I've to realize a VPN (ipsec) between 2 side that use a Router Cisco 1841, each one with its own public IP.The 2 side can ping each one with Public IP but the VPN are in DOWN's state.The schema is the following:
192.168.1.0/24 (LAN1) <-> Ro1 (X.X.X.X) <- VPN -> (Y.Y.Y.Y) Ro2 <-> 192.168.2.0/24 (LAN2)
the configuration of Ro1 is showed of following, the same configuration is present also in Ro2 but with different IP address

I looked but could not find any information on what's the use of the USB interface on my 2801 router. I saw something about Cisco USB memory module and eToken by Aladdin. Is this interface restricted to Cisco and Aladdin only?

I have a Cisco RV110W small business router setup at my home. It has one of those HTML GUI interfaces, check the boxes, etc.., to get things working. Basically, your typical home router with VPN. I have enabled the VPN, it's PPTP, added the password, and now it's automagically configured! I can successfully VPN to my home with a Windows7 client. Here's my problem, I now need to VPN into my home router with a 2801. Is this possible? Everything I found on the subject has only been to setup a Cisco IOS router as a VPN server or tunneling to another IOS router. No examples using an IOS based router as the client.

I have a Cisco 1841 serving as a connection between my ISP and my Firewall (non Cisco).
I seem to be having performance issues with my traffic going through the Router.HTTP (web browsing) is fine andI get my download rate as I would expect for a 10mbps connection.But anything to do with my VPNs I find a delay when sending via the 1841.(all my VPNs are managed by my Firewall and I have never had problems with those).
I also have a legacy ADSL connection to my firewall, which bypasses the 1841 and I am having no issues on that at all.If anything it is quicker! Which is madness as my Fibre should out-perform it easily.This leads me to believe the issue is not with the Firewall.
My 1841 is very simply setup, 2 fa interfaces with simply a default gateway setup within it.Which leads me to ask if I need more static routes in or a dynamic route protocol setup?

I'm having trouble setting up a Cisco 2801 as an internet router between our firewall & our ISP.I've setup FastEthernet0/0 as the WAN port & FastEthernet0/1 as the LAN port. I've setup a default gateway pointing the next hop (the ISP),when I plug in a pair of laptops configured to mimic our IP scheme, I'm able to ping thru, but when I put the router between our firewall & ISP I'm not able to get out to the internet (can't ping google) I can still ping the next hop.,Our old router died, so I am unable to pull up its configuration. Here is the code I'm come up with so far.

I have to configure failover on both router. if one get fail then the other router should be dial.Physical connection
•1. Two routers (Cisco 2801) are connecting with splitter through RJ 11 port.
•2.Only one ISP link is coming in splitter.
Requirement: As per as customer requirement. He wants redundancy with in both 2 routers. If one goes down then the other router come up. And same configuration on 2801_R2 router. I am planing to do HSRP on our lan network (2801R1,2801R2 ehternet interface which connected to switch). from switch i will create two default route with (next hope) virtual ip address.

I have a 2801 router with a HWIC-3G-cdma card that I have inherited from a predicessor. How to use a cellular card on a router and need to get this thing up and running. Any example config that I can see or point me in the right dorection to get this up and running? I have the cellular card set up as Cellular0/1/0 on the interface, I assume that that was done by default, and it has an IP address. The Static Route of 0.0.0.0 0.0.0.0 Cellular0/1/0, in the config with only 2 other interfaces as being direct connection. But that is as far as I recognize. Do I need to set up a router protocol? Which one? How do I use the cellular card? Do I need to have an ISP connection?

I have just received Time Warner Cable and get 16Mbps down from them directly through their modem (motorola DOCSIS 2.0 modem- SB5101) to my PC (using speedtest.net). When I then connect TWC's modem through my 2801 router on fa0/0, the download rate I get is considerably slower (on the order of 3-4Mbps via same testing method). What am I missing?
Here is how the passthrough interface is setup:
interface FastEthernet0/0
bandwidth receive inherit
ip address dhcp
ip nat outside
ip virtual-reassembly in
duplex auto
speed auto
I have attempted removing bandwidth command - nothing changed with it not there. I have also hard coded the speed and duplex to 100/full to no avail....
Other possible relevant configs:
ip nat inside source list 1 interface FastEthernet0/0 overload
ip route 0.0.0.0 0.0.0.0 dhcp
access-list 1 permit 192.168.1.0 0.0.0.255
Basically this things is wide open... for testing but the download speed differential is perplexing to me.

I have 5 routers. Four routers are: c2801-IPBASEK9-m v 12.4(24)T2. One router is a C2800-IPBASEK9-M v 12.4(24)T3. so, it appears that the IOS on all 5 routers is very similar, the only difference is the T3 at the end of the version and that 4 are 2801s and one is a 2800. What is very wierd is the 4 2801 have the embedded scripting language "tclsh". The 2800 does not have tclsh. If I issue the command: tclsh on the 2800, I get:
Center-GW#tclshTranslating "tclsh"
% Bad IP address or host name% Unknown command or computer name, or unable to find computer addressCenter-GW#

I have problems with the Router 2801.When i give the command show processes cpu, the command show me that the router is working in 98%.
I have vlans like voice vlan and others, I have one 20 Mb Wan Link and I redirect all traffic from my lan to this link and when i browse in internet or i do downloads the router goes to 98%, when i don't make it the router processes goes down.
I thought be problem with hardware, but i exchange to another router and the same problem happened.Before this situation, I had one link with 12 Mb and nothing happened, when i exchange this to the 20 mb link the problems starting.

I have one problem doing a ping to a router lan interface, I have 3 routers (2801) connected between each other (separated 1 mile each), the link is established trough microwave signals (connected to the 2801 fast ethernet interfaces), every router has a connection to a LAN. One of them is located at headquarters.Last thursday I replace one of the router with a cisco 2901, i configure the router with the same configuration that was on the 2801, i power up the router and the 2 link were up without problems.One day after the noc called me to tell me that after i replace the router they can't ping the router IP lan interface on the new 2901 (before the replacement the ping was sucessful). I called one user the lan connected to that 2901, and they can do a ping to the router's LAN IP address.
I can ping the 2901 IP wan interfaces, I can ping the LAN users ip address, but i cannot ping the router LAN IP address, from my desktop, and neither the 2 routers 2801 connected to the 2901.I show the configuration on the 2901, I couldn't change it because i didn't have time to do that, but i'll change the configuration to use ipsec tunnels.The configuration as you can see, has a crypto map, but the acl used by the crypto map, only permits the interfaces ip address, so i think that doesn't work, so the traffic doesn't get encrypted, but i don't know if that is the problem why i can't do a ping to the lan interface.

I'm trying to backup my primary WAN with secondary backup connection - 3G WAN through Cellular 0/0/0.Point is that I need to track some external IP address on my primary interface, for examle 8.8.8.8. If it is not reacheable, then router brings up backup connection - 3G. This can be done by using dialer-watcher.Simple.But unfortunately my primary WAN interface is an FastEthernet, which is the coonected to a switch, switch to WAN . There is no dialer-watch commands on it. Thats sad .
One more time :
WAN -> SWITCH -> ROUTER(WITH 3G HWIC and Fa 0/0 connected to switch).

I'm using for a company network a 2801 Cisco Router. This router has 2 FastEthernet Interfaces connected on 2 ISP's and one VLAN for internal users. What acl should i use if for example one client from the lan is using a torrent client to download from the internet. I want just to specify a maximum download speed or to block that client to access the internet when it's trying to download something that can affect other clients from the LAN.

The goal is to add a 2801 router between a DSL modem and a switch and obviously still access the internet. I connected and configured as explained below and the results are:
- I am able to ping internet addresses from the 2801 router
- I am not able to ping internet addresses from userlaptop but I am able to ping LAN gateway (192.168.254.254)
I cannot understand why the internet requests from the user laptopuser are not routed to the internet but the router itself can access the internet.
INTERNET====DSLmodem=====CISCO2801=====unmanagedSwitch=====userlaptop
DSLmodem:
non-bridged mode and does the PPPOe authentication.

simple configuration of a 2801 Router. I have 2 internet providers with static ip's connected to F0/0 and F0/1 and one Vlan for LAN area. I would like to configure the router to use one primary line and just in case to use the back-up line. [code]
Now if detects that it hasn't cable link on the FastEthernet interfaces it's working. I'm using 2 wireless gateways to acces the internet each one connected on the 2 FaEth for simulating the providers. If i simulate an issue on the provider ( i've removed the sim from the wireless gateway) it doesn't pass on the second isp.I haved trying to configure with "IP Service Level Agreements " for failover / load balancing but the command "ip sla" is incomplete. I can't make an update of the IOS because the customer do not have an Service Contract with Cisco.

I have setup an eBGP session to a Cisco 2801 CE router. The BGP session establish, however, the session keeps resetting after 90 sec which is the BGP keepalive holdtime value.
On the PE router I found that the OutQ doesn't clear = 22 when doing a "sh ip bgp x.x.x.x summary" - Session reset at 1:30.When I filter the amount of routes advertized to the CE neighbor with the "neighbor x.x.x.x prefix-list out" - I see the OutQ clear = 0 and the BGP session remains up.
-Number of NRLI advertized without prefix filter = 172
-Number of NLRI after filter = 52
why the OutQ doesn't clear.

This is only a small portion of our network but my question is, can these 1841 routers handle a 45Meg connection? I thought these routers were designed for T1/E1 type speeds. I know I saw a router performance document somewhere that showed 1841's could handle 38.4MB of traffic and that is only with routing turned on. If anything else is enabled, like access lists, NetFlow or whatever, that number will decrease because of the capacity of the router. Am I correct in these statements? Any document or anything else that shows performance of these routers?

We have an ADSL2+ line from a WIC in a 1841, everything has been fine for the last few years and then the last few months the connection going down. When checking the interfaces the ATM0/0/0 is up up and the same for the dialer interface we are using, they are both up/up, but this still needs a reload of the router to be functional again, shutting the interfaces does not bring the connection back up.
I am not an expert on ADSL lines, I have never really had a problem with anything previously. The router was running Netflow to a network monitor wondering if this or logging was causing an issue with entries in the buffer??
Here is an output of show dsl int, would change the firmware, it has been fine all this time before though we are running IOS 12.4(24)T1 advseck9-m, as far as I can seen from our ISP the config for ADSL is all correct. [Code]

I have two 1841's connect to the Internet via DSL;
fa0/0 --- 1841-R1 --- DSL1 ---------------------[INTERNET]--------------------- DSL1 --- 1841-R2 --- fa0/0
I am on the LAN attached to fa0/0 on R1 and I need layer 2 connectivity to a device on fa0/0 on R2. I'm not sure if this is possible with 1841's or not? I made a GRE tunnel between the two and was going to add a BVI and bridge the tunnel at each end with fa0/0 at eah end, but the 1841's don't support BVIs so I'm a bit stumped here! Would L2TP work here?
R2 is a remote router running C1841-SPSERVICESK9-M. R1 is local running C1841-ADVENTERPRISEK9-M. I can't change the remote router so if the answer is not support in C1841-SPSERVICESK9-M I won't be able to do this.
