I have three Hub routers that I'm wanting to compare DMVPN scalabiltiy capabilities (3825 versus 3945 and 3845). I know it must be there somewhere and I'm just not looking in the right place. But I've read and read and read about DMVPN designs and I'm not finding anything. This is turning into a time killer. What are the DMVPN limitations of these three routers are?
View 6 RepliesI am setting up a DMVPN between several dozen sites using 2800, 2900 and 3900 series ISRs. The DMVPN Design Guide recommends current 12.4 or 12.4T IOS, but the DG was last updated in July 2008. I cannot seem to find any recommendations newer than this. I'm hoping Cisco or the community can give me an updated recommendation.

Can the Cisco 819 router.URL provide the same functionality? What about the Cisco 866VAE router URl.

Now organization proposal is:
- Use MPLS and use an extranet network. Advertise a certain unique route to each partner..
- Grant unique VPN ID for each partner and VRF Lite at the data center. Then bring each partner with separate tagged VLAN to the data center via MPLS.
Can VRF Lite scale to more than 300+ partners OK?

I have a problem with my routers (cisco 1941)I'm running a DMVPN network (Hub and spoke)All the hubs are connected to the 2 hubs. With 4 tunnels. (each hub has 2 interfaces to the spokes. the spokes only have one interface to the hubs, so I splitted them and so I now have 4 dmvpn tunnels). one of the interfaces on a hub malfuntioned and because of that the customers had problems with logging in and sending packets. I made this kind of structure because of when one of the tunnels failed the spoke could use the 3 others... BUT, what happened here was that the spoke still tried to use all 4 of the tunnels and because of that I had 25% package loss!So this didn't work. Now I read about IP SLA, but I was wondering of this could work? (I cannot test it on spare routers, and I don't want to implement it and risking a total network failure...) and how to configure it. Should I make 4 different sla processes which I should all 4 track? And when I make the ip routes, how should I make or configure it so that 1 of the tunnels/interfaces fails that the spoke would addapt the routes?
View 1 Replies View RelatedI have a setup with two Cisco 877's – 1 for the hub and 1 for the spoke. The hub has a static WAN IP and the spoke has a dynamic WAN IP. The two sites are tunneled with DMVPN and cert auth for connections via Cisco VPN Client (terminating on hub router). All routes between the two sites work fine – I can see through both ends via LAN IPs and tunnel IPs. I can connect externally through Cisco VPN Client and RDP into PC's on the spoke end via local IPs.
My issue is: I want a port forward on the hub router, pointing to the IP (172.16.1.X) of a device on the spoke end. So using the WAN IP of the hub router, I can reach a host on the spoke side. At this point I cannot get this to work and feel it's related to a NATing issue. Here is my current config for both sites:
HUB Router:
!crypto pki server vpn-ca database level names issuer-name CN=*** CA,OU=*** Services,O=*** lifetime crl 336 lifetime certificate 7305 lifetime ca-certificate 7305 lifetime enrollment-request 1000 database url nvram!

I have a DMVPN network with 2 hubs (2821's). This setup is used for VoIP applications over the Internet for teleworkers. At the main hub site I used to have only 1 Internet feed which was DSL with a static IP. Now I have 2 WAN feeds for this site - 1 FTTB w/ PPPoE & the DSL with static IP. Since this site also hosts a PRI, I want all voice communications to go through the FTTB link instead of the DSL for obvious reasons, but keep the DSL as DMVPN Hub for all NHRP lookups as this link has a static IP address & is very stable. We originally put the PRI router as a DMVPN spoke which connected through the FTTB link, with another router acting as the DMVPN hub on the DSL link. This was obviously a waste of machinery. I want to combine both routers into one. So I tried something like this (don't laugh):
Gi0/0 to FTTB (Dialer1 connects to Internet)
Gi0/1 to DSL (Public IP towards 877 demarc)
Tun0 attaches to Dialer1 public IP and connects to other spokes, no VRF
Tun1 attaches to Gi0/1 public IP and acts as DMVPN hub (ip nhrp map multicast dynamic) under VRF "Hub"
EIGRP AS 1 is set up twice, once under router eigrp 1, and the other using router eigrp 2 using an address-family under the Hub VRF.This kinda works but obviously Tun0 & Tun1 do not speak to each other. I also had to remove the ip nhrp map instruction that pointed to Hub1 on Tun0, as this was causing a weird condition in the router where it was repeatedly trying to connect a tunnel to itself, and crash the router because the NHRP process would go haywire. So my users must rely on the Hub2 to get a NHRP lookup for the PRI site. If Hub2 goes down, everything works in the network except for tunnel connections to the FTTB link. I'd rather not have to configure 2 tunnels on each spoke router unless I really have to.
I am trying to spec out some routers for a small DMVPN network.I was thinking 2801's for my hub routers.will these run DMVPN out of the box or do they need additional hardware modules?according to the below linkyou need a "AIM-VPN/SSL-2" module in order for it to work, but then according to"The Cisco 2800 Series supports IPSec Digital Encryption Standard (DES), Triple DES (3DES), Advanced Encryption Standard (AES) 128, AES 192, and AES 256 cryptology without consuming an AIM slot."

View 3 Replies View Related I'm trying to configure and DMVPN architecture with two routers ASR1006 to server a bank remote offices, one ASR in CO building and the other in CA building (CO: Operational Center; CA: Recovery Center).Each ASR have two LAN connections to internal network and two WAN links to remote office. Each WAN links belongs to differents provider.Each remote office has a router with two WAN links connected to that WAN providers.We are configuring the DMVPN considering two primary tunnels in the CO building and two failover tunnels in CA building.We made the configuration (schemas and configuration attached) but we only get two tunnels up at a time. We cannot ping from office router to four tunnels interfaces in both hubs.
We made some test disabling some tunnels and we could get communication only with two tunnels interfaces. We got communication through tunnels when we have just two.We want to have the four tunnels for high availability. We would like to know how to troubleshoot and make a design review because the examples and documentations are very limited.
Trying to setup a DMVPN on out existing equipment that is currently running all point to point vpn connections. basicly its not working. my best guess is something with the config is interfering but i'm not sure the remote router (881) is always comming back with MM_NO_STATE and the main router(2901) is either MM_NO_STATE or MM_SETUP.
I added the config for the 881, 2901 and a debug crypto isakmp and debug crypto ipsec from both routers. I have verified the Keys are correct and it is not blocking port 500. if i issue a sh crypto isakmp policy they are the same on both routers. if you need me to post anything else i will, one note i removed the configs that were part of the point to point tunnls on the 2901 router.
Is DMVPN supported on Cisco 7200 XVR NPE-400, and would the NPE-400 module support QoS, multicast etc. I found an old doc mentioning DMVPN and this specific module.
View 1 Replies View Relatedone of my customers wants to implement VoIP in his existing DMVPN Network Topology. I have read about the "Per-Tunnel QoS for DMVPN" but when it comes to configure it on my hub router (Cisco 7206VXR with c7200p-advsecurityk9-mz.124-15.T14.bin) I am lacking the option to set the "ip nhrp map group" command.
My question now is, is it generally not supported by the 7206VXR platform? Or can I get the option by upgrading the IOS to a newer version? If so, which one could I use ?

I'm also able to Ping from my LAN to any Spoke Tunnel IP, but Im not able to ping any LAN IP at Spoke site nor am I able to ping my LAN from any Spoke site.

Imagine 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.
