PIM Configuration

To configure the threshold-dr option such that the data from S addressed to G must exceed an average of 1500 KBytes per second before an SPT switch is initiated. If this router is a DR for the pair (S,G), then the same data must exceed an average of 1500 KBytes per second before an SPT switch is initiated. The period over which the average will be calculated will be the mrt-periodtimes the mrt-spt-mult, or 60 seconds.

Blackbox/configure/ip/pim> threshold-rp 1500

To specify that the message checksum will be calculated over the entire encapsulated packet, rather than just over the Register message header, enter:

Blackbox/configure/ip/pim> whole-packet-checksum

The following example configures a global assert-holdtime value of 600.

Blackbox/configure/ip/pim> assert-holdtime 600

To set the holdtime to 60 seconds, enter:

Blackbox/configure/ip/pim> hello-holdtime 60

To set the hello interval time to 145 seconds, enter:

Blackbox/configure/ip/pim> hello-interval 145

To set the priority to 15, enter:

Blackbox/configure/ip/pim> hello-priority 15

To set the holdtime to 30 seconds, enter:

Blackbox/configure/ip/pim> join-prune-holdtime 30

To send messages every five minutes, enter:

Blackbox/configure/ip/pim> join-prune-interval 300

To check the router table every 15 seconds, enter:

Blackbox/configure/ip/pim> mrt-period 15

To set the mrt-spt-multvalue to be ten times that of the mrt-periodvalue, enter:

Blackbox/configure/ip/pim> mrt-spt-mult 10

To set the time out (S, G) entries at 5 times the mrt-period value, enter:

Blackbox/configure/ip/pim> mrt-stale-mult 5

To display PIM global configuration settings, enter:

Blackbox/configure> display ip pim global
