wait to receive a Hello PDU from the primary router before they

MIB Object ID: 1.3.6.1.4.1.18.3.5.17.1.17
Parameter: Good Bid Count
Default: 3
Range: 1 to 10
Function: Specifies the minimum number of good bids to become primary that are
required from the same secondary router before Auto Role Switching
occurs.
Instructions: Enter a number from 1 to 10 or accept the default of 3.
MIB Object ID: 1.3.6.1.4.1.18.3.5.17.1.12
Parameter: Bid Duration
Default: 45 seconds
Range: 1 to 65,535 seconds
Function: Specifies the number of seconds during which routers bid to become
primary router.
Instructions: Select a value in the specified range or accept the default of 45. This value
depends on how fast the router reboots with the configured features. For
example, booting with FDDI interfaces, WAN interfaces with resources
configured (such as servers and printers), OSPF, and so on, may require a
larger value.
