I 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.
View 1 RepliesI 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.

View 4 Replies View RelatedI 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?

i have a public AS from a ripe along with 2 Class Address (Public independent)
1) what is the best design and configuration to utilize the 3 Links ,outbound and inbound (since we have our public address along with AS) my boss told me,all These 3 links must be active
2)what is the recommended design and configuration for the whole topology , pls share the best gotchas

I have 3945 Router and I have bought NM-16ESW-1G1G card. After installed the card no interface shows on show ip interface brief or Show run command . When i end the switch module then i have found the interface. previously i have worked on NM-16ESW card on my 3845 router where interface card interface shows in my show run and interface command and i have assign IP and crypto map fro my Branch.
So my question is NM-16ESW-1G1G is different then NM-16ESW card ? if not then why i can not find interface. if Different then i have need to configure interfcae by enter the switch module seperately ?
Recently I came across a router (Cisco 3845, IOS 12.4) configured for TACACS, one local username and an enable password. Going through the configuration I noticed the router didn't have an enable secret password which I thought was strange.

Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

how can i route their network they have bring new router.
I have 2 x Cisco 3845 each one with a DS3 circuit, both running c3845-spservicesk9-mz.124-15.T3. In each of them I have one pvc provided by my carrier and I received the following info to configure:
vc-class atm ATM
vbr-nrt 44096 44096 1
oam-pvc manage
oam retry 3 10 1
encapsulation aal5mux ip
That worked fine for the first one with the NM-ATM-DS3, however, using NM-1A-T3/E3, it seems that I'm restricted up to 40700 kbps PCR/SCR:
router(config-vc-class)#vbr-nrt ?
I tried to look for some reference but couldn't find... Is there a way I can have a full DS3 with this card?
We have 3845 Router which is using for only Internet connectivity with one ISP(X) Customer has only one Vlan, Public AS number, and Public IP pool.Scenario:User--> L2Access-SW--> L3 (6500) SW--> Firewall (5520) --> IPS--> 3845Router.Now we have another ASR Router, which also has Internet connectivity from another ISP(Y).Now the issue is we would like to use both ISP in active/active scenario.
View 1 Replies View RelatedI am replacing our core router, which is a very old 7204VXR, with a T3 card in it. We are using it to terminate about 10 point to point T1's. It is also the central gateway for our entire network.
I am planning on replacing it with a 3845, and an NM-1T3/E3 card for my DS3. I think I've got that part worked out.
My real question is concerning future upgrades. We are trying to convert many of these point to point connections to Metro Ethernet, and get rid of the huge DS3 cost. When that happens, I'll probably have a handful of point to point T1's left over (maybe 2-6 of them). So, what I need is a good solution to terminate those 2-6 PTP T1's in my 3845. In the past I have just been using the old WIC-1DSU-T1-V2 cards to terminate my T1's. I am looking for a solution that won't break the bank. I looked at both the HWIC-4T1/E1 and the NM-8CE1T1-PRI cards (which terminate 4 and 8 T1's), but they are like $4,500 and $8,500 respectively. That's way beyond my budget for these. I definitley don't need a card that will do PRI's (DSP's etc.). I just need it to terminate plain old point to point T1's.
So it may be that I'm just looking at the wrong cards. Or maybe the make cards that will go in the back of the 3845 that will house 2, 4 or more WIC slots, and I could just use WIC-1DSU-T1-V2 cards?
I am upgrading from an old 7204VXR to a 3845. I am running a DS3 in the 7200, channelized into 28 point to point T1's. I need to break them all out into individual Serial interfaces on the new 3845, like I have on the 7200, but I don't know the correct commands.

I 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.
1841 & 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 ? .

I have a 3845 that will not let me ping to the internet from my PC.On interface g0/0 I have a connection to a internet connection (another router), using DHCP to get it's address (it gives g0/0 IP 192.168.0.3).On interface g0/1, I have a connection to my LAN (I assign the interface IP 10.10.1.1).
I can ping the router. The router can ping the internet, do DNS resolution, etc.I have ensured routing is enabled. The only route I have configured is a default static route: 0.0.0.0 0.0.0.0 192.168.0.1.Oddly, if I choose 0.0.0.0 0.0.0.0 g0/0, I cannot ping sites on the internet from the router.
I tried setting up ip nat inside for my LAN and ip nat outside for the WAN/internet uplink, but this did not work.
This was the issue, I missed finishing the NAT setup.I can make the router ping out all day, and have my PCs ping the router, but getting the connection between the two is not working.
Imagine on a 3845 router, I need to bond 2xDS1 circuits (for a Metro Private Line, point-to-point circuit).

We have a 3845 router at one of our remote sites. We want to connect the router to our central office using the two gigabit ports. One link would be the primary and the other would be the secondary (backup).
The router is running EIGRP and the two ports would have different ip addresses. How can we set up the router to use gi0/0 as the primary port and gi0/1 as the secondary (backup) port? The backup port would only be used if there was congestion on the primary port or if the primary port went down. Is there a way to force the router to make the primary link the best route?
Remote Router Sample Config:!
int gi0/0
desc primary link to Central Office

I am switching to a single Ethernet hand-off from my ISP which currently gives me 4 T1 lines. I have a Cisco 3845 router that services the current T1s. My question is since my ISP is giving me just a single Ethernet hand-off going forward can I connect it directly to the internal NICs on the 3845 or do I have buy some other HWIC?
I will be running a 100Mbps connection over the hand-off and the NICs are Gigabit NICs. I will not be doing anything fancy over this, just simply a couple of routes in the routing table. No VPN, no fire walling, etc. The specs state that the 3845 is only for up to a T3 speeds but I am not sure if that is for the HWIC interfaces or for the whole thing in general?
