Non-RFP traffic on 6500

[yatao]

We are going to implement multicast on our campus network. Planing to use PIM sparse mode. I read about the problem with non-RFP traffic for 6500/8500, we do have redundent stub network with 6500, Sup1A MSFC, hybird mode. I am quite confused by the different documents I read, I am wondering anyone can point me to the right direction on how I should handle this in my situation, using hardware ACL? Netflow rate-limit? what is the relation of non-RFP MFD of SUP-II with this? Any show commands I can use to check config and status of non-RFP traffic?

Thanks,

Yatao

Hi Yato,

one of our customer had the same problem. And we decide with Cisco to implement the setup under the following link:

Hope this help.

Thanks for the reply.

Did your customer see the problem before you apply the access-list? When I tested in the lab, I did see the multicast traffic were sent to the Non-RPF interface on the standby MSFC, but I didn't see any CPU spike, probably my traffic was too low to have any impact, 30pps.

Also in the following link, Cisco said from 6.2.1 onwards, system automatically apply the ACL. I am using 6.3.5, do I still have to manually apply the ACL?

Thanks again,

No, our customer didn't see any problems because we done it before activating multicast. As far as I know Non-RPF MFD is supported with Supervisor Engine 2 only.
