Fix Recommendation

Configure the RP to rate limit the number of multicast register messages it will allow for each (S, G) entry.

[edit protocols pim rp]
set register-limit maximum nnnnn

Check Contents

Review the configuration of the RP to verify that it is rate limiting the number of multicast register messages.

protocols {
…
…
…
}
pim {
rp {
register-limit maximum nnnnn;
local {
address 2.2.2.2;
}
}

Note: Each any-source group (*,G) counts as one group toward the limit. Each source-specific group (S,G) counts as one group toward the limit.

If the RP is not limiting multicast register messages, this is a finding.
