We want to terminate new 10M link via Ethernet interface on Cisco 1841 router. We have free Gig port on the router. We also have HWIC-FE module inserted in the router. However, our implementation team said that Cisco 1841 doesn't support 10M link. It is not designed to cater to such high Bandwidth.
View 14 RepliesOn our ASA 5510 we already have one ISP link terminated on outside interface. There is correspoinding nat and global configured for outbound access to internet.
Now we need to terminate second ISP link on one of the DMZ interface to have redundancy for the primary ISP.
When primary ISP link or router is down we need to send all the traffic to secondary ISP router. How do we configure NAT and global for this condition that only when primary is down then only this NAT -Global should be used. Do we have anything like object tracking associated with the NAT-global.
So that as long as Primary RTR - object is up ASA will use the first NAT-Global pair. When primary ISP is down RTR-Object is not reachable then ASA will perform the second NAT-Global operation.
Also can we have default route pointing to Outside interface (primary ISP router) and in case of primary router failure it will point to secondary ISP. Do we have "track" in the static route commands on ASA.
I'm looking to use a Cisco 3945E to terminate a 1Gbps Ethernet internet connection and I want to know the realistic throughput that I can expect. The router will only be configured with BGP with partial routes. No firewall or QoS will be configured.

What are the possible effects of assigning an invalid address like 172.22.0.0 255.255.255.252 to a router interface. The 1841 router accepted the address?
View 12 Replies View RelatedWe have a 1841 Cisco router for one of our remote sites and we have the GRE over IPSec tunnel on it (with our datacenter router) for the connectivity. The LAN facing interface becomes UP/Down (status 'UP', Protocol 'Down'). When I login the router and 'shut' and then 'no shut' the interface, the interface becomes UP and everything starts to work. Traffic starts to flow across it. But after some time, some hours or sometimes some days, the interface is again back to up/down status. The router is connected to a non-Cisco switch.

I am trying to figure out how to use a Cisco 1841 IOS router to take traffic from one interface and source NAT it out towards the Internet on one interface and at the same time NOT perform NAT when sending the traffic towards a different routed interface.
Here the RemoteSite has connectivity back to the MainCampus, but there is no need to NAT traffic from the one site to the other. They share the same umbrella of address space. However, the RemoteSite needs to have its Internet-bound traffic NAT'ed out to the Public Internet via a third interface. I know that I could just NAT everything out from the Remote Site and map the traffic back onto the same address space for intra-campus communication, but I'd rather avoid that and just NAT where I need to NAT it to the Internet.
I do have a caveat here: in the event that either the MainCampus or the Public Internet interfaces go down, I would like to failover traffic from the downed link to other good link. For example, I want to NAT all traffic (including "intra-campus" traffic) out via the Public Internet if the direct link to the MainCampus is down. For the other example, if the Public Internet direct link is down, I would just send out all traffic without NAT towards the MainCampus.
I have a Cisco 1841 that has an ADSL (ATM) card installed. It was previously used with an ADSL line to provide NAT routing for an office. Now I want to use it witha cable modem, which would mean abandoning the ADSL interface and instead routing between the two Ethernet ports.Between the Cisco and the LAN is a Linux transparent proxy. It provides routing between 192.168.1.0 (LAN) and 192.168.2.111 (Cisco LAN interface). The network looks like this:
Cable Modem(174.76.21.1)(gateway) --- (174.76.21.10)(WAN) Cisco 1841 (LAN)(192.168.2.111) --- (192.168.2.11) Linux Proxy (192.168.1.10) --- (192.168.1.0) LAN
For testing and diagnostics, I've connected a laptop to each FastEthernet port on the router. One laptop is configured with the IP 174.76.21.1 to simulate the cable modem gateway and the other laptop has the IP 192.168.2.11 to simulate the Linux proxy. From those systems I've performed the following diagnostics with the following results:
From 192.168.2.11
Ping 192.168.2.111 - OK
Ping 174.76.21.15 - OK
Ping 174.76.21.1 - Timed out
From 174.76.21.1
Ping 174.76.21.15 - OK

There are some vestiges of the ADSL configuration, but I've cleaned most of it out and shut down the ATM interfaces. Here's my config:

my company will change WAN connection from HDSL (2Mb/2Mb) to Metro Ethernet (10Mb/10Mb). Now, I have CISCO 1841 (12.4(15)T12 ) with 2 FE and HWIC-1T. Can i configure my Metro Ethernet (WAN Connection) on one FE or i need of "external wic" such as hwic-1FE ?
View 1 Replies View RelatedI have a cisco 1841 router in place. I also have a ADSL module which fits into the cisco router. My understanding is that if configured correctly, If the primary circuit were to fail (Ethernet Circuit MPLS), the ADSL would take over services until such time the ethernet link becomes available.
Therefore the ADSL circuit is used as a resilient link. If this is possible, can the Cisco 1841 be setup to automatically switch over to the ADSL? Would there be some sort of heart beat between the ethernet circuit and adsl circuit?Also from the other end of the Cisco router, the connection goes into a firewall. If the Cisco handles the failover, I assume I would not need to configure anything on the firewall.
The end users beyond the firewall, should be able to continue, however the performace would be degraded?
I am trying to roll out a new internet router. The problem I am faced with is the LEC only supports VLAN 1227 and greater, specifically they are assigning me VLAN 2528. I am able to create the sub-interface and setup dot1q encapsulation for VLAN 2528, but the vlan database does not have the ability to add VLAN 2528 to it so I am unable to get layer 2 up and going, thus preventing me from getting the implementation done.
View 11 Replies View RelatedI use an 1841 router as an internet facing firewall with a 10MB MetroE connection. Lately users started reporting slow internet download speeds and web pages timing out. Bandwidth reports do not show the link as being saturated so I looked at the interfaces on the 1841. The interface connected to the provider shows OK as far as errors but the LAN side of the router shows steadily increasing input errors. It doesn't show any other errors, no CRC, frame, runts, giants or overruns, just generic input errors. What type of errors are those? Nothing is being logged on the console.
I moved the connection to another switch ports and the errors continue. I switched it down to 10MB and also changed the switch and the errors slow down but don't stop. Interestingly, the switch side never shows any errors. What can I do here? I guess it can be a bad interface but that is such a rare thing that I am hesitant to replace the router.

View 1 Replies View RelatedI have an 1841 between my firewall and the ISP. Three interfaces - multilink to ISP, FA to my firewall, and FA to my inside network. I use the inside interface for configs aand snmp access, etc. Only my ISP-assigned fixed address block will get routed to the multilink by the ISP but I am nervous about the inside interface sitting on my LAN. I know I can remove it, but if I keep it there, how can I set up an ACL so that all traffic from the multilink interface is denied to the inside interface? I suppose another way to think about it that the inbound iface can only accept traffic from its own outside, not from the router.I think this is fairly simple but I don't want to knock down the traffic if I get it wrong.

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]
