Basic Question on Site-to-site vpn connection ...

[InternetB]

Hi,

I have a basic question on site-to-site vpn.

I have a setup whereby,R1 is connected to the Internet and I want to create a site-to-site vpn to R2 and R3.

My question is can I create sub-interfaces on R1 so that I can create site-to-site vpn with R2 and R3 ? Thereby making R1 as the hub ...

Would be great if there is a doc showing this. Tried finding this on the Doc CD but to no avail.

Thank you,

Cheers,

InternetB.

To answer - NO on the sub-interfaces.

You could use tunnels and run a dynamic routing protocol over the tunnels

or use DMVPN
