mode gre
This parameter a) specifies the tunnel
encapsulation method as GRE and b) allows
you to specify whether it is a Layer-2 or Layer-
3 GRE tunnel.
l <16-bit protocol number>
The 16-bit protocol number uniquely
identifies a GRE tunnel. The number format
is numeric. The controllers at both endpoints
of the tunnel must be configured with the
same protocol number. The protocol number
does not necessarily have to match the
protocol number of the encapsulated frame.
The controller encapsulates the entire
frame, including the Layer-2 header.
l ip
Specifies an IPv4 Layer-3 GRE tunnel. The
protocol number is set to 0x0800 and is not
configurable. Traffic is redirected into the
tunnel using a static route or a session ACL
policy. The controller encapsulates the
Layer-3 packet only.
l ipv6
Specifies an IPv6 Layer-3 GRE tunnel. The
protocol number is set to 0x86DD and is not
configurable. Traffic is redirected into the
tunnel using a static route or a session ACL
policy. The controller encapsulates the
Layer-3 packet only.
