Final answer:
When a remote IP link fails, the system may reroute traffic through an alternative route or activate a backup link, if these are configured. Otherwise, traffic could stop, or a diagnostic process might start to resolve the issue.
Step-by-step explanation:
When a remote IP link fails, the outcome can vary depending on the network configuration and the protocols in place. Typically, one of the following can happen:
- The system reroutes traffic through a different route if alternative paths are available and the routing protocol is configured to find the next best path.
- The system might initiate a diagnostic process to identify the cause of the failure and to attempt to resolve the issue.
- Traffic could stop flowing altogether if there are no alternate routes or failovers configured.
- If a backup link is in place and properly configured, it can activate automatically to maintain connectivity.
In modern networks, both rerouting traffic and backup link activation are common strategies for maintaining network reliability.
