Supported Platforms QFabric System
Syntax no-make-before-break;
Hierarchy Level [edit fabric routing-options multicast]
Release Information Statement introduced in Junos OS Release 12.2 for the QFX Series.
Description (QFabric systems only) Disable the default make-before-break multicast feature on
QFabric systems to prevent the duplication of system traffic. This feature increases the
speed of data plane traffic, but carries the risk of minor traffic losses when compared
with the default make-before-break method of creating new multicast fabric paths
before tearing down the old paths. The absence of the
no-make-before-break
configuration
statement implies that the make-before-break default system behavior is in effect.
Required Privilege
