Abstract
As required by Routing Protocol Criteria [1], this report documents
the key features of Triggered Extensions to RIP to Support Demand
Circuits [2] and the current implementation experience.
As a result of the improved characteristics of Triggered RIP, it is
proposed that Demand RIP [5] be obsoleted.

The authors wish to thank Johanna Kruger and Jim Pearl of Xyplex for
many comments and suggestions which improved this effort.
1. Protocol Documents
"Triggered Extensions to RIP to Support Demand Circuits" [2] suggests
an enhancement to the "Routing Internet Protocol" (RIP) [3] and
"RIP-2" [4] to allow them to run more cost-effectively on Wide Area
Networks (WANs).
2. Applicability
Triggered RIP requires that there is an underlying mechanism for
determining unreachability in a finite predictable period.
The triggered extensions to RIP are particularly appropriate for WANs
where the cost - either financial or packet overhead - would make
periodic transmission of routing (or service advertising) updates
unacceptable:
o Connection oriented Public Data Networks - for example X.25 packet
switched networks or ISDN.
