Configure IP routing and forwarding
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.
Include this interface in RIP advertisements
Select to cause the subnet configured on this interface to not be advertised by RIP.
