Release Information
Statement introduced in Junos OS Release 12.1.
Description
Configure the designated forwarder (DF) election offer period for bidirectional PIM. When a DF election Offer or Winner message fails to be received, the message is retransmitted. The offer-period statement modifies the interval between repeated DF election messages. The robustness-count statement determines the minimum number of DF election messages that must fail to be received for DF election to fail. To prevent routing loops, all routers on the link must have a consistent view of the DF. When the DF election fails because DF election messages are not received, forwarding on bidirectional PIM routes is suspended.
If a router receives from a neighbor a better offer than its own, the router stops participating in the election for a period of robustness-count * offer-period. Eventually, all routers except the best candidate stop sending Offer messages.
