Please help to advise on the ports to configure guard root so that Sw1 can remain as the Root, in the event the priorities of Sw2, Sw3, Sw4 or Sw5 are reduced.
For both examples, please assume all else are equal (priority, link cost, etc).
For Example 1, should I place guard root on
Sw1 F0/1 and 0/2?
Sw2 F0/2 and F0/3,
Sw3 F0/2 and F0/3?
For Example 2, should I place guard root on
Sw2 F0/3 and F0/4,
Sw3 F0/3 and F0/4,
Sw1 F0/1 and F0/2?
Sw2 F0/2, F0/3, F0/4,
Sw3 F0/2, F0/3, F0/4?
Any other combination is welcomed.
