Configuring Interface and Router Redundancy

2-4 114079 Rev. B

The primary router periodically monitors itself to make sure it is functioning

normally. If the primary router is not functioning properly, a role change occurs,

as follows:

1. The primary router notiﬁes the best secondary router that it intends to change

out of the primary role.

2. The best secondary router informs the other members of the impending role

change, and those members start a timer (using the Bidding Timer value) to

prevent additional role changes by other members.

3. The best secondary router assumes primary status.

able 2-2 describes how a primary router changes to a secondary role while the

best secondary router assumes the primary role.
