Create GRE tunnel over IPSEC in OSPF

[inderjeeta]

Hi Team,

How we can configure the GRE tunnel over IPSEC when we are using the OSPF.

My requirement is to configure the GRE tunnel over IPSEC between the Central router and three remote sites which is connected to central site. What's the configuration that I need to do in Central as well as remote router to create GRE Tunnel over IPSEC?
