Brocade FastIron Ethernet Switch IP Multicast Configuration Guide - Manual (Page 222)

You must configure four parameters indicating the four different route types. If you want to specify that a
particular route type not be used, configure the none keyword to fill the precedence table.
Examples This command specifies a non-default route from the mRTM, then a non-default route from the uRTM,
then a default route from the mRTM, and then a default route from the uRTM.
Device(config)# router pim
Device(config-pim-router)# route-precedence mc-non-default uc-non-default mc-default
uc-default
This command specifies that the unicast default route be ignored.
Device(config)# router pim
Device(config-pim-router)# route-precedence mc-non-default mc-default uc-non-default

route-precedence admin-distance
Specifies that multicast routes are selected from the best route from the multicast routing table
(mRTM) and the unicast routing (uRTM) table.

Command Default The default is route-precedence mc-non-default mc-default uc-non-default uc-default.
Modes PIM configuration mode
Usage Guidelines The no form of this command removes the configuration and restores the default route precedence
settings.
If both the mRTM and the uRTM have routes of equal cost, the route from the mRTM is preferred.
Examples The following example shows how to specify that the best multicast route from the mRTM and uRTM
tables is selected.
Device(config-pim-router)#route-precedence admin-distance

show ip mroute
Displays information on multicast routes. You can specify whether you want to display information
from static or connected mroutes or from a particular mroute.
