RIPv2: Triggered Updates

Triggered updates in RIPv2 are sent at the same moment a router detects a change in the reachability of a network, instead of waiting for the Update timer interval to expire.

  • Connecting to a new network
  • Learning about a new network
  • Disconnecting from a network
  • Learning about a networks unreachability

These will all trigger an update immediately and send advertisements about this change to neighbors.  The triggered update will only carry the affected networks information without listing all the other networks normally seen in the standard update messaging.

Triggered updates are also referred to as flash updates.
