Abstract
In a network device comprising redundant management processors and one or more linecard processors situated on one or more linecards, a linecard processor maintains multicast information that is synchronized with multicast information, or a portion thereof, maintained by an active management processor. When a switchover is performed due to which a previous standby management processor becomes the new active management processor, the switchover is performed without interrupting any multicast routing services provided by the network device. For example, a switchover may be performed in order to upgrade a linecard processor to a new software version.
