Cisco WAN :: 2851 / DMVPN As Backup For MPLS Circuit
Jan 10, 2011Imagine you have 5 sites, one router each site (2851 as CE) connected to MPLS network. All sites have max 3xT1.Requirement:In case CE router or circuit to MPLS fails in any of those sites, I need to provide backup circuit to reach MPLS network.
Proposal:Bring one Internet circuit to each of those sites and create DMVPN to every site.
Question:Let's say Site1-MPLS circuit goes donwn.
Then all traffic from Site1-MPLS should flow thru the IPSec tunnel to all other MPLS sites. Am I right that the traffic coming from Site1-MPLS will ingress via the 2851 CE routers, correct? Is this the typical design? How to accomplish this, I'd like to setup a lab to simulate it.
Cisco WAN :: 2851 - Using BGP With VRF's To Emulate MPLS And Internet
Nov 6, 2012I am setting up a lab network to emulate our production network and am using a single 2851 to emulate both my MPLS provider (only running BGP, not actually running MPLS) and our ISP that we use for our DMVPN secondary network.
Because I am using one router to function as both service providers I am running VRF's to keep the routing tables separated. So far basic connectivity works fine, I can ping from the PE 'MPLS' VRF to the data center CE interface and the ISP side is working as well.
Pinging across the ISP VRF
lab-isp#ping vrf TW 66.193.134.46Type escape sequence to abort.Sending 5, 100-byte ICMP [code]...
BGP is up from both the data center MPLS CE and the data center internet router. BGP on the data center internet router:
lab-dc1-inet#sh ip bgp summ
BGP router identifier 66.193.134.46, local AS number 33415
BGP table version is 4, main routing table version 4
[code]...
BGP on the data center MPLS CE
lab-dc1-1#sh ip bgp summ
BGP router identifier 10.152.1.250, local AS number 65000
BGP table version is 2, main routing table version 2
[code]....
This is my first attempt at using VRF's in this fashion and could have easily missed something or used a config that is not necessary.
Here is the configuration on the MPLS PE/Internet router.
ip vrf CL
rd 1:1
route-target export 1:1

Cisco WAN :: 2921 - Site2site VPN As Backup For MPLS
May 14, 2013I am designing a remote site that will have MPLS as primary and a site2site as backup, both connections on the same 2921 router. My problem is monitoring the connection status of the connections? Testing reachability to the MPLS router at the data center would allow bringing up the VPN, but once the VPN is up the data center router is reachable again. Is there a way to track reach ability through a specific interface?

Apr 16, 2013I thought I saw a post/question in regards to "how to" configure a Broadband backup for a MPLS circuit.. What I am trying to do is use a cable/dsl/ broadband (secondary) connection as a backup to a MPLS circuit (primary). I have EIGRP and BGP configured on both the branch endpoint and the tunnel headend. The tunnel is used by the interface that connects to the secondary circuit. The branch location router is a 1841 and the "headend" tunnel router is a 3825. I am wondering about the configuration/syntax of a "weight" or static route that can be used to have data flow over the tunnel when the MPLS circuit goes down - and then switch back to the MPLS circuit when it comes back on line.

May 24, 2013setting up MPLS on a single T3 line. A client has contacted us to set up a 2951 at a branch location. There are 5 locations connected with MPLS.They will split off 4meg of the T3 for mpls. The rest of the 45meg would go to the internet.They have two 1841's currently set up with a T1 line in each. One 1841 connects to the MPLS and the other to the internet.When the T3 is turned up by the provider, everything, internet and MPLS, will go through it. I asked for the current configurations, but I have not received them yet and this setup is due in a couple days.Given I've never configured MPLS before and I have a rudimentary understanding of how it works, any tips or configurations? I'd hate to be stuck on site and not equipped to complete the job.

Cisco WAN :: Licensing For IOS 15.x On 2851 Routers?
Feb 16, 2012Do I need to obtain license keys/files when upgrading a 2851 to IOS 15.x? I'm getting a bit confused seeing the documentation that says 1) IOS has gone to a universal image and 2) that feature sets are unlocked based on the installed license.
I was able to download a feature specific IOS image for the 2851 and it did not bother me about licensing upon boot up.
I read one post on here that stated 2800/3800 series (G1) do not have to worry about the licensing piece and that it's just 2900/3900 series (G2) hardware that require it.

Cisco WAN :: 2851 - How To Route / NAT Based On IP With 2 WAN Connections
Mar 29, 2012I have a Cisco 2851 (with a 4 port switch module) that I am trying to set up with two different internet connections, and have it route traffic out to them based on the source IP. One connection is a 50mb Comcast connection, another is our T1 that our servers are hosted on. The goal is to guide server/phone system traffic to the T1 and have the rest default to the Comcast. I currently have the 2851 connected to our Layer 3 switch (Dell Powerconnect 6224) with a subnet created between them. Static routes have been created on the 2851 back to all of our existing subnets. Traffic flows internally without a problem between the subnets and 2851 (and vice versa). I set up the 2851 with route-map's in the NAT to control the flow of traffic, with the default route set to the Comcast connection. Default route works great, speedtest shows full speeds and everything looks great. The problem happens when I apply my route-map policy to the internal LAN interface with the ACL list of IP's that I want to guide to the T1 (with a next-hop of the T1's IP address). I tested some tracert's and pings from one of the IP's in this list and they would stop at the T1 modem and not go any further. I did a "show ip nat translations" and noticed that the "outside" portion (right half) was blank for every IP that was in the ACL or related to the T1. So my guess is it looks like this is not doing NAT for the T1? I double-checked that I had my "ip nat inside" on the LAN interface and "ip nat ouside" on the T1 VLAN interface and Comcast interface and they were there.

Nov 12, 2012I recently obtained a 2851 and have been battling this issue for a week now. An odd set of circumstances happen with the bootstrap startup process. If the router has loss of power or when reloaded; it fails to read the CF card and boots to rommon. I can tftp an image to it (tftpdnld -r) and IOS CAN read the flash card along with any saved configuration.In fact once in IOS, I can wr mem and print the hardware details of the CF card. Once I reload the router it goes to rommon, fails to open the flash, then sits until i tftp the image back. When the router load IOS, it also loads the startup config.I don't think it's a problem with the CF card as IOS can read it. I've tried formatting the card from IOS and from my pc as FAT, FAT16, FAT32, and NTFS - it didn't make a different. I updated the ROMMON to allow for USB booting but haven't purchased a USB Drive yet for testing. The upgrade didn't resolve this issue either. It almost seems like a firmware problem with the EPROM.

Cisco WAN :: 2851 How To Make Spoke Going To Hub To Get To Internet
Mar 23, 2011Imagine MPLS network. Total of 4 sites.
HQ-HUB is the only site with access to the Internet.

Would you do this based on DNS settings or getting an access-list & static route defining when the spoke routers traffic need to go the internet, point to the HUB-HQ as the default?
