[c-nsp] ip multicast rate-limit

[Arie Vayner (avayner)]

Zenon,

Can you please explain specifically what you want to rate limit...
Maybe a show ip mroute could be helpful...

Hi Arie,

I would like to ask you something:

The ip multicast rate-limit command, when used with a group-list and/ or source-list argument, does policing on a per-mroute (S,G or *,G) basis. This is according to relevant IOS documentation and this
document:

ftp://ftpeng.cisco.com/ipmulticast/config-notes/multicast-rate-limit.txt

The above (perhaps outdated) document suggests (in section "Status") to use CAR for per-interface (aggregate) traffic rate-limiting, but to keep using this command for per-mroute applications. Has this changed since 2001?

Could you suggest how to build a policy that would apply at per-mroute (or higher, i.e. per-flow) granularity, instead of being applied on the aggregate matched traffic?

Would this sort of granular policing fall within the scope of the microflow policing feature, which is available on some 7600 and Catalyst 6500 hardware?

Best regards,
Zenon Mousmoulas
