Module: HPICFHIGHAVAILABILITY-MIB
OID (symbolic): HPICFHIGHAVAILABILITY-MIB::hpicfHAContinuousFwdingTime
OID (numeric): 1.3.6.1.4.1.11.2.14.11.1.11.1.2
Node type: OBJECT-TYPE

Description: This is a configurable timer. After the failover, on the new AMM, the route and neighbor table entries are marked as stale in the FIB. As routing protocols begin to re-add routes, this stale flag will be reset. When this timer expires, all route and neighbor table entries still marked stale [not yet re-added] will be removed. A value of 0 means that no layer 3 hitless behavior is desired, and in this configuration, upon failover all FIB entries are flushed and corresponding hardware entries are removed. A default value of 5 minutes is chosen with the assumption that the routing protocols can finish re-adding the routes to the equivalent state within this time.
What is hpicfHAContinuousFwdingTime?
This configurable timer, in seconds, controls how long route and neighbor table entries are kept marked "stale" after a management module failover before being flushed from the FIB if routing protocols haven't re-added them. Admins tune this to balance hitless failover behavior against stale-route cleanup: setting it to 0 disables layer-3 hitless failover and flushes the FIB immediately, while a longer value gives routing protocols more time to reconverge before removing entries. With the default value of 300 seconds, if OSPF hasn't re-added a route within five minutes after failover, that stale route and its hardware entry are automatically removed.
