Field Reference

PIM Page - Bidirectional Neighbor Filter Tab

A PIM bidirectional neighbor filter is an access control list (ACL) that defines the neighbor devices that

can participate in the bidirectional trees and designated forwarder (DF) election. If a PIM bidirectional

neighbor filter is not configured for an interface, then there are no restrictions. If a PIM bidirectional

neighbor filter is configured, only those neighbors permitted by the ACL can participate in DF election

process.
