Choice of VRRP master router

About initial priorities for routers and how they determine which router is the VRRP master router.

The purpose of the modifications to the VRRP state and priority is to adjust which router is the VRRP master.

Take care so that initial priorities across routers are within the adjustment range.

  • If Router A has a base priority of 200 and an adjustment of 10 while Router B has a priority of 150 and an adjustment of 10, then Router A will become master with an effective priority of 210 when it's tracked monitor/path pair is compliant.
  • If Router A's tracked monitor/path becomes non-compliant then it will remain as master, as it's base priority is higher than Router B's effective priority.
