Applications are either supported or unsupported by stateful SRP switchover.
Supported—You can configure supported applications without having any adverse
impact to stateful SRP switchover. When a switchover occurs, supported applications
can react to switchovers in one of two different ways:
Gracefully recover using mirrored static and dynamic information (for example, IP,
PPP, and PPPoE)
Recover using static configuration only; that is, no runtime state is restored after a
switchover. Dynamic configuration and state information are lost. (For example, CLI
sessions are restarted, telnet sessions are dropped, multicast routes must be rebuilt,
and so on.)
Unsupported—We recommend that you not configure unsupported applications on a
chassis running in high availability mode. Although configured unsupported applications
suspend high availability or prevent high availability from becoming active, they do not
cause any problems with the function of the router.
Table 8 on page 42 indicates which applications support or do not support stateful SRP
switchover.
