Send RIP advertisements on this interface
Check this box to enable RIP and to reveal further configuration parameters below.
Use RIP
RIP version level. Select from the values V1, V2 and V1 Compat (version 1-compatible). When
RIP version is set to V1 or V2, the router 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 router 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 behavior.
• 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:
Selects the authentication method for RIP packets. Only one option is enabled multiple
selections are not possible.
None
When set to Off, the interface sends and receives packets without any authentication.
Access list
When set to Access List, the interface sends RIP packets without any authentication. When
receiving packets, the interface checks 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 is allowed through.
