GRE TUNNELS
GRE TUNNEL CONFIGURATION
GRE is the abbreviation of Generic Routing Encapsulation and it is a standard encapsulation used
to establish tunnels between interfaces of two systems, connected either directly or remotely.
The activation of a GRE tunnel requires the configuration of the following parameters:
 the name of the GRE tunnel interface
 the IP address of the physical interface on which the tunnel will be activated (tunnel-
source)
 the IP address of the remote physical interface towards which the tunnel will be terminated
(tunnel-destination)
 the local IP address to assign to the tunnel (tunnel-address)
 the remote IP address to assign to the tunnel (tunnel-peer)
Optionally, for each tunnel configured, it is possible to set the following parameters:
 MTU (Max Transfer Unit)
 TTL (Time to Live)
 Multicast (enable multicast transmission)
 keep-alive: it is possible to enable keep-alive functionality by configuring the
parameters keepalive-intval (interval for sending keep-alive packets) and keepalive-
retries (maximum number of lost keep-alive packets before the tunnel interface is
terminated)
Starting from the 5.4.5-4 software version, the maximum number of tunnels configurable is 256; le
previous versions have only 8. The syntax is:
set gre tunnel X <options>
where x can be 0 to 255
Below you find the main configuration commands, where it is used the notation
set gre tunnel 0 <options>
but the same commands are applied with:
set gre tunnel 0 <options>
set gre tunnel 1 <options>
....
set gre tunnel X <options>
In order to establish the name of the network interface associated with the tunnel the following
command is used:
set gre tunnel 0 name <name>
