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 routing devices 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 routing device receives from a neighbor a better offer than its own, the routing device stops participating in the election for a period of robustness-count * offer-period. Eventually, all routing devices except the best candidate stop sending Offer messages.
Options
milliseconds—Interval to wait before retransmitting DF Offer and Winner messages.
Range: 100 through 10,000 milliseconds
Default: 100
Required Privilege Level
