number of DMVPN spokes

Hi,

There are some hard limited number like number of ipsec tunnel, encryption throughput for ISR G2, You can find it from

http://www.cisco.com/en/US/prod/collateral/modules/ps2706/ps12202/data_sheet_c78-682436.html

In term of the max number of spokes 2950 can support for DMVPN design, you also need to consider the routing protocol, features that will be enabled, authentication/encryption mode. We have some internal scalability testing document of ISR G2 for DMVPN, please reach out your cisco SE for that information.

Let's put it another way, how many do you need? For example 20 or 200 is no big deal, while 2000 may need some care in design.

Hi,

to be precise, I need a router that can be a hub for 325 dmvpn spoke routers. Any advice?

People from the local Cisco office recommended me ASR1000, but it is a very expensive device.

The number of spokes will have an impact on router load, but how much traffic will be passing across DMVPN  tunnels perhaps even more so.

Cisco recommends a 2951 for up to 500 IPSec tunnels, and 103 Mbps, see Table 7 in attachment.

Re: number of DMVPN spokes

Can any one confirm how many IP sec tunnel support by Cisco 892 router ?

 

Re: number of DMVPN spokes

Hi Zubair,

 

890 routers support the maximum of 50 IPSec tunnels with Security license. Maximum IPSec throughput can be 125 Mbps but the maximum speed of WAN circuit supported is 15 Mbps.
