Cisco WAN :: BGP Configuration With 3845?
Dec 31, 2011I have two routers 3845 and HSRP is configured properly. Currently we are using default route to ISP and right now I want to use BGP as I have 3 Public pools and that's why I want to advertise in the public network. How I can configure that in my Router.

Dec 13, 2011I have a 3845 that I am trying to configure but it won't save. It doesn't matter what i do (write mem, copy run start). No matter what, if I reload it, it wipes the config. Am I missing something, or is it just a bad memory? I don't get any errors when I save, it looks like it takes, but no dice.

Sep 19, 2011I have a 50 Mbps metro ethernet connection between our main office, and our collocation site, where we store web servers, DR equipment and VPN access gateways. I have two Cisco 3845 ISR's connected to the metro E circuit. The interfaces on each router are configured as 100/full as requested by my ISP. We are connected via ethernet to a fiber media converter.
As I understand, CBFWQ will not kick in until congestion occurs on an interface. I also understand that the bandwidth command on an interface is to provide bandwidth related information to upper level protocols (like EIGRP, etc).
My question is that since the interface where I have CBWFQ configured on is at 100 Mbps, but my circuit is at 50Mbps, how can I get my routers to kick CBWFQ in when traffic demand exceeds 50Mbps+? Does the bandwidth command on the interface control that as well?

Mar 24, 2011I am installing Cisco blank CF upgrades (double the capacity of the CF that came with the router) in Cisco 3845 routers and I cannot get the IOS to load.
Network security requires tftp be disabled, so I am limited to xmodem. Slow, but it works. I know the IOS download is good, because I can load it on the CF that came with the router.
I can install, format and read the new flash. But the download locks up and bombs about 1/3 of the way through.
Note: CF that came with the router was "C" so I used the format flash: command. The new flash reads the same as the old, except that there is no file IOS loaded.
I've never had an issue upgrading an IOS, but this is my first shot at installing on a new CF.
Cisco :: Use 1841 Router Instead Of 3845?
Apr 26, 20111841 & 3845 router. We send 30 GB data on 100 Mbps link. First time we use 3845 router for sending the data and 47 Min are required to complete the data, during this link utilization was 100%. After that we send same data through 1841 router & 46 Min are required for the same. Only difference in data transfer is CPU Utilization of 1841 router goes 30% & 5 % of 3845 router Can we use 1841 router instead of 3845 router ? .

Cisco WAN :: 3845 - Select NTP Server Version On IOS Router

ntp server 192.168.1.1 prefer
ntp server 192.168.1.2

I see that the router is sending out NTP version 4; however, my NTP server is configured to accept only NTP version 3. Anything other than version 3 will be dropped.
How do I go about to configure NTP on the Cisco IOS router to send out only version 3 and not version 4?
Cisco :: 3845 Router - DFM 3.0.2 False Alert On E1 Controller
Jul 20, 2011I have the following problem with DFM 3.0.2:
One of my customers has got a Cisco 3845 router with some E1 controllers in it. DFM sometimes generates an alert that says the controllers are flapping, meanwhile there is no syslog, or snmp-trap generated in the router itself. If the cables disconnected/connected, or a shut/no shut command was issued ont the interfaces, the router generates the syslog and snmp-trap as it is required.
So in a nutshell it seems that there is no flapping ont the controller, but for some reason DFM thinks that there was one.
I searched for bugs, but wasn't be able to find anything relevant neither in DFM, nor in the IOS itself (c3845-advsecurityk9-mz.124-24.T2.bin)

Apr 27, 2011My company recently failed a PCI scan because our router was returning 56bit des encryption for isakmp negotiation on an existing default isakmp policy. How do I remove this default isakmp policy. I am not running 12.4(15)T1 so the no crypto isakmp policy default does not work. Is there any way other than upgrading the IOS?
Is there any way to configure a maximum number of isakmp policies that an authenticating router will check? I have 2 configured higher priority ISAKMP policies. Maybe if there is a command to limit the number of isakmp policies the router checks, that would eliminate this default policy being matched?
