Configuring Interface and Router Redundancy

3-4

308626-14.00 Rev 00

Table 3-1 demonstrates what happens when you configure interface redundancy

across slots using router and interface redundancy together.

Note that you can prevent the second role change by configuring the Automatic

Role Switching parameter to Switch on Failure or One Shot Auto (refer to

Chapter 5).

Using the Clear Function

The Clear option from the Router Redundancy pulldown menu allows you to clear

all protocols from all circuits that have router redundancy configured. The Clear

option does not clear any protocols from circuits that are not configured for router

redundancy. This option is useful when you convert a primary router redundancy

configuration to a secondary configuration, because a typical secondary

configuration does not include any of the protocols that the primary has.

To access the Clear option, choose Protocols > Router Redundancy > Clear in the

Configuration Manager main window.

Table 3-1. Using Interface Redundancy across Slots with Router Redundancy

Router A Router B

Router A is in the primary role for router

redundancy. It also has the active interface in the

interface redundancy group.

Router B is in the secondary role.

The CPU board for the active interface fails.

Router A detects that it is no longer the best

primary router, so Router A changes its role to

secondary.

Router B is the new best primary router, and it

assumes the primary role.

Meanwhile, a redundant interface from the

interface redundancy group has become active,

with the result that Router A is again the best

primary router in the router redundancy group.

Router B recognizes that it is no longer the best

primary router and changes out of the primary

role.

Router A assumes the primary role. Router B is in the secondary role.

Data is moving again.
