PIM Configuration
113
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-period times 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-mult value to be ten times that of the mrt-period value, 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
