Monitoring and Maintaining IP Multicast Routing
These sections describe how to monitor and maintain IP multicast routing:
•
Clearing Caches, Tables, and Databases, page 40-51
•
Displaying System and Network Statistics, page 40-52
•
Monitoring IP Multicast Routing, page 40-53
Clearing Caches, Tables, and Databases
You can remove all contents of a particular cache, table, or database. Clearing a cache, table, or database
might be necessary when the contents of the particular structure are or suspected to be invalid.
You can use any of the privileged EXEC commands in Table 40-4 to clear IP multicast caches, tables,
and databases:
Step 3
ip dvmrp metric-offset [ in | out ]
increment
Change the metric added to DVMRP routes advertised in incoming
reports.
The keywords have these meanings:
• (Optional) in —Specifies that the increment value is added to
incoming DVMRP reports and is reported in mrinfo replies.
•
(Optional) out —Specifies that the increment value is added to
outgoing DVMRP reports for routes from the DVMRP routing
table.
If neither in nor out is specified, in is the default.
For increment , specify the value that is added to the metric of a DVMRP
router advertised in a report message. The range is 1 to 31.
If the ip dvmrp metric-offset command is not configured on an
interface, the default increment value for incoming routes is 1, and the
default for outgoing routes is 0.
Step 4
end Return to privileged EXEC mode.
Step 5 show running-config Verify your entries.
Step 6 copy running-config startup-config (Optional) Save your entries in the configuration file.
