22. Configuring Generic Routing Encapsulation
Revision 1.14.3 206 RX1000/RX1100™
Note
Each tunnel must have a unique combination of local and remote addresses, or it will not be
activated.
The Cost field configures the routing cost associated with networking routing that directs traffic through
the tunnel. The cost will default to zero if left unset.
The Local Egress Port configures a port to bind the tunnel to. If set, tunneled packets will only be
routed via this port and will not be able to escape to another device when the route to the endpoint
changes.
The Tunnel MTU field allows you to configure the MTU (Maximum Transmission Unit) value. This is
useful in preventing the fragmentation of GRE packets.
