The router is started.
As periodical RIP update is disabled, the confirmation and retransmission mechanism is required to
ensure that update packets are sent and received successfully over the WAN. The retransmit-timer
and retransmit-count commands can be used to specify the retransmission interval and maximum
retransmission times for request and update packets.
The function can be enabled in the case of the following conditions: a) The interface has only
one neighbor. b) There are multiple neighbors but they interact information using unicast
packets. You are advised to enable the function for link layer protocols such as PPP, frame
relay, and X.25.
You are advised to enable split horizon with poison reverse on the interface enabled with the
function; otherwise invalid routing information might be left.
Make sure that the function is enabled on all routers on the same link; otherwise the function will
be invalid and the routing information cannot be exchanged correctly.
To enable the function, make sure that the RIP configuration is the same on both ends of the
link, such as RIP authentication and the RIP version supported by the interface.
If this function is enabled on this interface, the source address of packets on this interface will be
checked no matter whether the source IP address verification function (validate-update-source)
is enabled.
The following example enables TRIP and sets the retransmission interval and maximum
retransmission time to 10 seconds and 18 respectively for Update Request and Update Response
packets.
Ruijie(config)# interface fastEthernet 0/1
Ruijie(config-if-FastEthernet 0/1)# ip rip triggered
Ruijie(config-if-FastEthernet 0/1)# ip rip triggered retransmit-timer 10
Ruijie(config-if-FastEthernet 0/1)# ip rip triggered retransmit-count 18
