RIP Direction RIP (Routing Information Protocol) allows a router to exchange routing information
with other routers. The RIP Direction field controls the sending and receiving of
RIP packets.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the ZyXEL Device will broadcast its routing table
periodically.
When set to Both or In Only, the ZyXEL Device will incorporate RIP information
that it receives.
When set to None, the ZyXEL Device will not send any RIP packets and will ignore
any RIP packets received.
By default, RIP Direction is set to Both.
RIP Version The RIP Version field controls the format and the broadcasting method of the RIP
packets that the ZyXEL Device sends (it recognizes both formats when receiving).
Choose RIP-1, RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is
probably adequate for most networks, unless you have an unusual network
topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the
difference being that RIP-2B uses subnet broadcasting while RIP-2M uses
multicasting. Multicasting can reduce the load on non-router machines since they
generally do not listen to the RIP multicast address and so will not receive the RIP
packets. However, if one router uses multicasting, then all routers on your network
must use multicasting, also. By default, the RIP Version field is set to RIP-1.
Enable Multicast Select this check box to turn on IGMP (Internet Group Multicast Protocol). IGMP is
a network-layer protocol used to establish membership in a Multicast group - it is
not used to carry user data.
Multicast Version Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast
Protocol) is a session-layer protocol used to establish membership in a Multicast
group – it is not used to carry user data. IGMP version 2 (RFC 2236) is an
improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If
you would like to read more detailed information about interoperability between
IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236.
Spoof WAN MAC
Address from
LAN
You can configure the WAN port's MAC address by either using the factory
assigned default MAC Address or cloning the MAC address of a computer on your
LAN. By default, the ZyXEL Device uses the factory assigned MAC Address to
identify itself on the WAN.
Otherwise, select the check box next to Spoof WAN MAC Address from LAN and
enter the IP address of the computer on the LAN whose MAC you are cloning.
Once it is successfully configured, the address will be copied to the rom file
(ZyNOS configuration file). It will not change unless you change the setting or
upload a different ROM file.
Clone the
computer’s MAC
address – IP
Address
Enter the IP address of the computer on the LAN whose MAC you are cloning.
If you clone the MAC address of a computer on your LAN, it is recommended that
you clone the MAC address prior to hooking up the WAN port.
