Route selection precedence for multicast
he route-precedence command allows the user to specify a precedence table that dictates how
routes are selected for multicast.
PIM must be enabled at the global level.
Configuring the route precedence by specifying the route types
The route precedence {mc-non-default mc-default uc-non-default uc-default none}* command
allows you to control the selection of routes based on the route types. There are four different types
of routes:
• Non-default route from the mRTM
• Default route from the mRTM
• Non-default route from the uRTM
• Default route from the uRTM
Using this command you may specify an option for all of the precedence levels.
