Cisco WAN :: IP SLA Configuration 2911

Feb 12, 2013

I have a router Cisco 2911 with two possible Wan interfaces out and a backup configuration using IP SLA. When the Primary Interface goes down the traffic is automatically rerouted through the Backup Interface, but the problem I have is that when the traffic is going through the Backup Interface (because the Primary is down) if the Backup Interface also goes down, if the Primary goes up, the traffic  is not automatically rerouted to the Primary Interface. And it looks to me like it keeps trying to goes out the Backup Interface and cannot see that the Primary is down. I guess that the pings are going out the backup Interface and as it is down the router doen't receive any anwer to the ping and doesn't change to the Primary.

The main configuration related to the IP SLA is this:
track 1 ip sla 1 reachability
interface GigabitEthernet0/0
description backup Interface
ip address 175.xx.xx.10
ip nat outside

Cisco WAN :: Stable IOS For 2911

Aug 5, 2012

We have 2911 with   HWIC-4ESW. System image file is "flash0:c2900-universalk9-mz.SPA.152-1.T1.bin"_2911#sh inv NAME: "CISCO2911/K9 chassis", DESCR: "CISCO2911/K9 chassis" PID: CISCO2911/K9      , VID: V05 , SN: FGL16011005


The problem was that HWIC-4ESW no longer pass traffic although showing that the interfaces are up rebooting the router solved the problem. What IOS is more stable and not subject to this problem?

Cisco VPN :: Zfw VPN Tunnel 2911

Mar 2, 2012

Recently i attempted to build a LAN 2 LAN VPN tunnel from an Asa to a 2911 running zone based firewall.  This was a standard IPSec psk tunnel nothing fancy.  I got the tunnel to establish but i could only get traffic to encap on the Asa side and decap on the 2911 side.  I couldn't get return traffic.I followed this doc here for classic IPSec in the last example. URL

And I am sure the Asa is right I built a ton of those but I am new to zfw.  I did not see anything about a NAT exempt rule.  But since everything uses real IPs instead of NAT I wasnt sure and I could not find any info.  Do I need to do NAT exempt?  If so do you use a route map on the end of you NAT overload config line like in the past?

Also I have a zone-pair to "self" and I was not sure if I needed anything there to be able to ping the inside interface of the 2911 when the tunnel is up from the remote end.

Cisco WAN :: Minimize IP Usage On 2911 And Keep NAT

Aug 1, 2012

I have a problem I am running into... I replaced a 2621 with a 2911. The 2911 has three interfaces and I need to use all of them... Description:
gige0/0 dhcp static IP from ISP, public IP, they assign me 4 more usable public IPs gige0/1 broken into four VLANS, 108, 109, 120, 127, ip nat on 109 for them to get to the internet, and a static translation on 127 for the phone system to get to the internet gige0/2 assigned another public IP. A tenent has a linksys router on this interface, they want a public IP.
The problem is that this setup worked, but when we moved to the 2911, some nat translations are failing, and we would like to figure out how to minimize the number of public IPs we use (right now it is three + the static assigned dhcp). The nat that is not working is the nats to the 2001-3001 range. I am not sure why it is failing, but the router seems to indicate it thinks some of these overlap. This router is also doing a vpn to an asa... that seems to be working fine.  
Current config:
Current configuration : 6072 bytes

Cisco WAN :: 2911 / Configure BGP Over The ADSL?

May 19, 2011

I've got a 2911 with a primary ethernet link to the ISP, with BGP running over it.  There's also an ADSL module in it, which will connect into the same ISP AS. how do i configure BGP over the ADSL so that it sits there doing nothing until the primary link fails?  Do i need to setup a new instance of BGP with a different AS on the router or can it sit in the same AS as the primary link?

Cisco WAN :: Can't Configure Serial Int On 2911/K9

Feb 1, 2012

Were bringing up a new site shortly and I'm trying to configure Serial0/0/0 which will be connected to an MPLS over 1.5m T1 line.  I am basically doing a simular configuration as other sites where one of the ethernet interfaces is handed off from a fiber optic wan, but a T1 MPLS is connected to a WIC card and this provides a redundant path (though slower) in case of a fiber cut or equipment failure.  This should be pretty straightforward but it appears as if I have no serial interface on this router.  Card is in and everything, it is a VMIC-3-1MFT-T1/E1 in EHWIC 0.

Cisco WAN :: Tweaking Config On 2911 ISR G2 With ZBF

Apr 14, 2012

I'm working on tweaking the config on a 2911 ISR G2 with a ZBF and am looking for some input.  Our main issue right now is that the router is having performance issues once we hit certain troughput thresholds.
Right now, I have an inside-outside inspect set to look at all FTP, TCP, UDP, ICMP, DNS, SIP and HTTP (I know, its a bit redundant) traffic and do inspection on it then pass all other traffic.  From a company policy, we are not filtering ANY traffic of any kind going outbound.  (I know this isn't best practice but that's another battle for another day.)
Additionally, I have an outside-inside policy set to pass GRE traffic to an internal PPTP server (I know, not secure but its what we have.) then I have another inbound policy to inspect all traffic coming through that matches a specific ACL that defines all of the holes we're poking for hosting various functions on internal servers, etc.
could I, should I, why would or wouldn't I simply pass traffic that matches specific ACLs or whatever instead of how we are presently doing a lot of inspection?If I was to simply pass matching traffic instead of doing the inspect, would I see a substantial performance increase/workload decrease ont he 2911?
What are the security ramifications related to simply passing traffic instead of doing the inspection?

Cisco WAN :: Setting Up New 2911 Router

Feb 18, 2013

Recently they bought a new Cisco 2911 router and told me that they want it connected to an outside WAN connection that they hadn't used in a while so they could create a little network on the side. They want to just plug the server into the router and go. Unfortunately, I am sort of clueless about how to set up the config for it.
There are 3 GE ports, with the line from the outside coming in on GE0/0. I've already activated the interface and it is up, but that's where I get stuck.

Cisco WAN :: 2911 / PBR Only Works With IP CEF Disabled

Jan 16, 2013

We have a PBR configured on a 2911 router (15.1-4.M2).  The PBR is being used to send specific traffic across a S2S VPN instead of an MPLS connection.  If ip cef is enabled, the router sends the traffic across the MPLS.  If ip cef is disabled, the traffic goes across the S2S VPN.  I checked to see if there were any bugs in the code they are running about this and nothing came up.  It almost like CEF enabled PBR isn't working on this device, even though it should be enabled by default when ip cef is turned on.

Cisco Firewall :: NAT For A Private IP 2911

Dec 20, 2012

We have some Cisco 2911's that we are configuring 2 VPN's ( second is for redundancy) We are pretty confident on the failover VPN setup using SLA monitoring.
One thing we are stuck on is the redundant VPN will be setup over a 3G connection provided by verizon. Verizon issues a Private IP ( 192.168.100.X) the far end device terminating the VPN has a public ip of 183.172.22.XX , what kind of NAT translation do I need to make this work ?  Also does Cisco have any good configuration examples for VPN Failover setups for Cisco 2911's?
