DMVPN/IPSEC GRE and IPSEC Multi Point

[satya mothukuri]

  Hi All

 I have a project to build connectivity from 50 locations to my 2 datacenter. Every location has Internet with Router 877 with sec image.

any my DC's has 1900 router. Now i want to which tunnel i have to go with. IPSEC GRE or DMVPN IPSEC .

Out data will come from locations to DC only. No inter location connections. I want to know advantages and disadvantages and any hardware change required.

Regards,

Given your criteria I would suggest DMVPN would be the best fit

Cisco - Configuring Dynamic Multipoint Virtual Private Networks DMVPN

Thanks Pete, we u think GRE will not have any advantage?

what abt hardware? will 1900 router can handle 80 tunnels.

GRE - is just the transport, it will get protected by IPSEC anyway :)

1900 does support it
