Packets that are forwarded out the same interface on which they were received do not traverse
the emulated WAN link. Packets are never forwarded between the MGMT and LAN A or LAN B
interfaces.
Routing Mode supports only the forwarding of IP frames and does not support multicast
forwarding.
Figure 7: Routing Mode
5.2.1 IP Addresses
In IP Routing Mode, an IP address and netmask must be configured for the LAN A and LAN B
interfaces. Use of the gateway field is optional. All addresses are entered in dotted-decimal
notation.
If a gateway address is set, it must be on the same subnet as the corresponding LAN A or LAN B
address. If a gateway address is set for only one interface, then the Linktropy WAN emulator will
use this address as its default next-hop router. When gateway addresses are set for both
interfaces, the default next-hop router for packets received on one interface is the gateway of the
opposite interface.
The following entries are invalid:
a gateway address not on the same subnet as the interface address
an interface address or gateway address with an all-zeros host component
an interface address or gateway address with an all-ones host component
