ipsec and gre tunnel

Hi everybody

Let say we have two sites,   s1 and s2.  We want to connect these two sides ipsec.

s1---internet----s2

The ip sec tunnel is configured between s1 and s2 via internet; Ip sec provides encryption and authentication.

Let say we want to replace  ip sec by GRE tunnel.  The question is will GRE tunnel provide  similar features ( encryption,authentication) the way ipsec does?

Thanks and have a great weekend.

NO

GRE is only provide a tunneling method of unicast or multicast traffic in a gre tunnel without encryption

Gre can be used with IPSec to add encryption to it

Hope this help
