I’ve a multicast financial market connected to my infrastructure, I’ve been
informed that a new data multicast flow could reach up to 6 Gbs, so an huge
amount of traffic needs to be replicated.
Market is connected to an ASR 1001, than to a C6807-XL and customers are
Even with fabric enable blades in the c6500, you are going to get massive
output buffer overflows. Market data has very uneven traffic patterns causing
microburst effects. What sup-engines/blades are on the boxes? What type of
multicast replication is being used (ingress/egress). QoS policies

I’m not able to find the multicast replication mode on ASR..
On core routers:
C6807 has Supervisor Engine 2T 10GE and IOS 15.1(2)SY4
Mod Ports Card Type Model Serial

A sustained 6Gps on a 10GB pipe is hard to do already, but with multicast….
Typically that large of multicast is broken up into different multicast
addresses can be split on multiple lines. The burst nature of the feed is going
to be an issue. Will it work, yes. Will it work well, I doubt it.
The 6748 blades are going to be an issue with buffer overruns. Whether this
will be a minor or major issue depends on the application that uses the

well we'll connect to 10 Gbs interface a traffic up to 6 Gbs, not on 6748 1
Gbs blades... no other issue you see ?

Do you have any idea what IOS version you had on your lab 7600 that you put the
config on ?
I've got 15.3(3)S6 on the box I'm testing on and whilst the commands exist:

Firstly, which kind of ASR are you looking at here?
