282 CHAPTER 28: RIP CONFIGURATION
Configuring TRIP In a connection oriented network, a device may establish connections to multiple
remote devices. In a WAN, links are created and removed as needed. In such
applications, a link created between two nodes for data transmission is temporary
and infrequently.
TRIP should be enabled when it is necessary to exchange routing information via
on-demand links or triggered RIP.
Enable TRIP
Follow these steps to enable TRIP:
n
If RIP is disabled, TRIP is also disabled.
Configure TRIP retransmission parameters
You can specify intervals and upper limits for Update Request and Response
retransmissions as needed.
For two routers on an analog dial-up link, the difference between retransmission
intervals on the two ends must be bigger than 50 seconds; otherwise, they can
not become TRIP neighbors.
Follow these steps to configure TRIP retransmission parameters:
n
The maximum retransmission time (upper limit × interval) for a packet cannot be
too long lest when its neighbor is down, the router still resends the packet.
