Hello Pekka,

We've for years now installed policers in our upstream/peering

Would you happen to have an example Junos configuration to do this
in global configuration?
Not sure about JunOS, but I believe this should do the trick for Cisco
IOS:
ip access-list standard SAP-mcast-group
permit host 224.2.127.254
deny any any
exit
interface X/Y.Z
ip multicast rate-limit in group-list SAP-mcast-group 1000
exit
This should be applied at (interfaces facing) the edges of your
multicast network. It effectively means that any sources the router
sees with a rate exceeding 1000 kbps, it will not forward downstream.
Sorry for digging up old emails (4 years later) but due to the latest SAP storm I just went and tried to check
ip multicast rate-limit in group-list SAP-mcast-group 1000
on 12.2(33)SRE6 and got:
This command is no longer supported
Ideas?
Thanks,
Hank
Sorry if it's slightly off-topic.
