Configuring IP routing and forwarding
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
n
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
n
selected for sending to the default RIP v2 multicast address 224.0.0.9.
<BLANK BOX>: Forces RIP packets to be sent to a specified IP or multicast address. This
n
setting 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.
Plain password
When set to Plain password (V1+V2), the interface uses 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 plain text 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 plain text key must be present in the packet before it
will be accepted. You can use this method with both RIP V1 and RIP V2.
MD5
When set to MD5 (V2 only), the interface uses 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 uses 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. You can
use this method 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.
Use Triggered RIP on this interface
Enables triggered RIP (RFC2091). When triggered RIP is enabled, RIP timers are disabled.
