Use RIP:
Select from the values ‘v1’, ‘v2’ and ‘v1 Compatible’ in the dropdown list. When RIP version
is set to ‘V1’ or ‘V2’, the unit will transmit RIP version 1 or 2 packets respectively (version 2
packets are sent to the “all routers” multicast address 224.0.0.9). When RIP Version is set
to “V1 Compat”, the unit will transmit RIP version 2 packets to the subnet broadcast
address. This allows ‘V1’ capable routers to act upon these packets.
Send RIP advertisements as:
Broadcasts:
RIP packets are by default sent out on a broadcast basis or to a multi-cast address. Do
not change this parameter unless you intend to alter this behaviour.
Multicasts (Only visible when ‘v2’ is selected in the ‘Use RIP’ option above):
This is automatically selected for sending to the default RIP v2 multicast address
224.0.0.9.
<BLANK BOX>
This parameter may be used to force RIP packets to be sent to a specified IP or multicast
address. It is particularly useful if you need to route the packets via a VPN tunnel. By
default Broadcasts/multicasts are selected – depending on your RIP version.
Use Authentication:
This parameter selects the authentication method for RIP packets. Selection is by clickable
radio button. Only one option is enabled multiple selections are not possible.
None:
When set to “Off”, the interface will send and receive packets without any authentication.
Access list:
When set to “Access List”, the interface will send RIP packets without any authentication.
When receiving packets, the interface will check the sender’s IP address against the list
entered on the Configuration – Network > IP Routing / Forwarding > RIP >
Global RIP settings > Access Lists page, and if the IP address is present in the list,
the packet will be allowed through.
Plain password:
When set to “Plain password (V1+V2)”, the interface will use the first valid key it finds
(set on the Configuration – Network > IP Routing / Forwarding > RIP > Global
RIP settings > Authentication Keys > Authentication Key n pages), and use the
plaintext RIP authentication method before sending the packet out. If no valid key can be
found, the interface will not send any RIP packets. When receiving a RIP packet, a valid
plaintext key must be present in the packet before it will be accepted. This method can
be used with both RIP v1 and RIP v2.
MD5:
When set to “MD5 (V2 only)”, the interface will use the first valid key it finds (set on the
Configuration – Network > IP Routing / Forwarding > RIP > Global RIP settings
> Authentication Keys > Authentication Key n pages), and use the MD5
authentication algorithm before sending the packet out. If no valid key can be found, the
interface will not send any RIP packets. Received RIP packets must be authenticated
using the MD5 authentication algorithm before they will be accepted. This method can be
used with RIP v2.
Only send RIP advertisements when this interface is in service:
Select this parameter for RIP advertisements only to be sent when the interface is in the UP
state in the routing table.
