Redundancy Groups
Configuring a Redundancy Group
8. After you have created a configuration for every RP in your network on every
active module, reset the RPs. The correct module should now adopt each RP.
Note If your redundancy group includes multiple standby members, you might want to control
which standby members adopt particular RPs if an active member fails. Assign every
standby member an adoption preference ID. Then set the IDs just as you would for a
group of active members. On every standby module, make sure that every RP has been
assigned one of the IDs used by standby modules.
As always, if the preferred standby member cannot adopt the RP, another standby
member will. However, the failover time might be slight greater while the other
members of the group wait for the preferred member to adopt the RP.
The following sections explain how to set the adoption preference ID so that you can
complete the procedure described above. You can set the ID for:
■ a module
■ an individual RP
■ all newly adopted RPs
