IPSEC Transport Mode

Hello,

I am fairly new to IPSec and have only ever done one tunnel deployment.

Question I have is can I runn the following configuration, and if so, does anyone have an example.

Router1 in London

Router2 in New York

IGP between sites

Can I sen data through the path of the NY and London routers say via a serial line but i dont want IPsec to wrap a new IP packet header around the packet?

Is this possible?

Many thx,

Ken

Re: IPSEC Transport Mode

Generic Routing Encapsulation (GRE) enables routing updates to be sent over the IPSec tunnel. Here is an example of OSPF configuartion with GRE.
