site to site vpn with dynamic ip on all locations

[nexus2010]

Hi,

I have 4 Cisco 877 routers, all with  ethernet (internal) and ADSL (external) interfaces. The IP address given to the ADSL interface is dynamic . I want to connect all the 4 lcations using this setup.

Can you please suggest a configuration sample or a document showing how to configure the VPN using the dynamic ips?

Thanks & Rgds

Unfortunately you can not build site-to-site vpn with the external interface having dynamic ip address. The only supported site-to-site vpn is dynamic to static site-to-site vpn, not dynamic to dynamic site-to-site vpn.
