Configuring Router Redundancy
114079 Rev. B 5-11
Parameter: Timeout Threshold
Default: 5
Options: 1 to 100
Function: Specifies the number of time periods during which the secondary routers
wait to receive a Hello PDU from the primary router before they
determine that the primary has failed.
Instructions: Enter a number from 1 to 100 or accept the default of 5.
MIB Object ID: 1.3.6.1.4.1.18.3.5.17.1.17
Parameter: Good Bid Count
Default: 3
Options: 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. This parameter has no effect is you have configured manual
role-switching.
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
Options: 1 to 65,535 seconds
Function: Specifies the number of seconds during which routers bid to become the
primary router.
Instructions: Choose a value in the specified range or accept the default of 45. This
value depends on how fast the routers boot 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.
Shorten this value if you want to ensure that the first router that boots
becomes the primary.
