Usage Guidelines

Usage Scenario

If a router ID conflict occurs in an OSPFv3 area, the system selects a new router ID, which prevents route flapping and reduces route calculation operations. Other protocols will not go Down when the CPU usage is controlled.

NOTE:

If the automatic recovery function is enabled and a router ID conflict occurs between indirectly connected routers in one OSPFv3 area, the system replaces the conflicted router ID with a newly calculated one. The automatic recovery function takes effect on both configured and automatically generated router IDs.
The system can replace a router ID in a maximum of three attempts in case the router ID conflict persists.
