mode gre
Specifies generic route encapsulation (GRE) type. You
configure either a 16-bit protocol number (for Layer-2
tunnels) or ip (for a Layer-3 tunnel). The 16-bit protocol
number uniquely identifies a Layer-2 tunnel. The
controllers at both endpoints of the tunnel must be
configured with the same protocol number.
— —
source
The local endpoint of the tunnel on the controller. This
can be one of the following:
l specified IP address
l the loopback interface configured on the controller
l specified VLAN
— —
vlan
VLANs to be included in this tunnel.

Usage Guidelines
You can configure a GRE tunnel between an Dell controller and another GRE-capable device. Layer-3 GRE tunnel
type is the default (tunnel mode gre ip). You can direct traffic into the tunnel using a static route (specify the
tunnel as the next hop for a static route) or a session-based access control list (ACL).
Example
The following command configures a tunnel interface:
(host) (config) #interface tunnel 200
ip address 10.1.1.1 255.255.2550
tunnel source loopback
tunnel destination 20.1.1.242
tunnel mode gre ip
