PROTOCOL INDEPENDENT MULTICAST DESIGNATED ROUTER NOTIFY DELAY FEATURE

摘要

Method and system for reducing multicast traffic loss including configuring, on a primary DR including a first configured DR priority, a DR parameter including a value and an attribute; sending to a secondary DR, after a PIM interface comes up, a PIM hello message including a default DR priority lower than a second configured priority of the secondary DR; sending to the secondary DR, after the primary DR reaches a system-up state, a PIM hello message including the default DR priority; performing DR functionality, by the primary DR, after reaching the system-up state; and sending to the secondary DR, after waiting a time period corresponding to the value of the DR parameter, a PIM hello message including the first configured DR priority, where the primary DR waits to send the last PIM hello message to the secondary DR after the time period based on the attribute of the DR parameter.

1. A method for reducing multicast traffic loss comprising:
configuring, on a primary designated router (DR), a DR parameter comprising a value and an attribute, wherein the primary DR comprises a first configured DR priority; sending to a secondary DR that is performing DR functionality, after a Protocol Independent Multicast (PIM) interface of the primary DR comes up, a first PIM hello message comprising a default DR priority that is lower than a second configured priority of the secondary DR; sending to the secondary DR, after the primary DR reaches a system up state, a second PIM hello message comprising the default DR priority; performing DR functionality, by the primary DR, after the primary DR reaches the system up state; and sending to the secondary DR, after waiting a time period corresponding to the value of the DR parameter, a third PIM hello message comprising the first configured DR priority, wherein the primary DR waits to send the third PIM hello message with the first configured DR priority to the secondary DR after the time period based on the attribute of the DR parameter.
