To avoid the encapsulation of multicast data packets from the first hop router to the RP, you can send the system a register stop message. You can specify the amount of time (in seconds) the RP monitors the number of register packets after sending a register stop message.
SEFOS# configure terminal SEFOS(config)# set ip pim enable SEFOS(config)# set ip pim rp-threshold 10 SEFOS(config)# set ip pim rp-switchperiod 15 SEFOS(config)# set ip pim regstop-ratelimit-period 10 SEFOS(config)# end
This example sets the RP to monitor the number of registered packets received for 10 seconds after a register stop message has been sent.
SEFOS# show ip pim thresholds PIM SPT Threshold Information ----------------------------- Group Threshold : 10 Source Threshold : 15 Switching Period : 5 PIM SPT-RP Threshold Information -------------------------------- Register Threshold : 10 RP Switching Period : 15 Register Stop rate limit : 10
