Subject: Re: [c-nsp] Drop rule at the end of CoPP conflicts with MAC
People running CoPP usually think of CoPP.
People that have run GSRs will also think of receive access lists.
Most right thinking ISPs should have rules that rate limit rather than drop the
connection.
CoPP is not a receive access list and should not be treated like one.

First step is determining what is actually hitting your control plane and
what the maximum traffic levels for that traffic should be.
For some platforms like the 6500 you have to deal with traffic requiring ARP
And ICMP responses as well as what should be hitting the cpu for control and
routing
infra exmem statistics
If the FIB overflows the DRAM, it will start using IRAM.
If the IRAM fills the ESP may become unstable and traffic is offloaded to the
RP.
I have not found a command to actually show the CEF information on the ESP.

You would put in aggregate summary-only for the ones you want to leak.
Each summary-only line will produce a route.

HSRP and GLPB requires setting up different groups for the dual stack.
The same groups can be used on different vlans but the IPv6 has to be in a
separate group from IPv4.

7600 will do EoMPLS with lan cards (best bet is pseudowire mode) but there are
caveats with vlan rewrite and things like that.
And of course the lack of support for Q in Q.

Community strings don't effect inbound traffic, right?
Is there really no good way to influence inbound traffic?

The ES+ cards are the way to go.
The OSM modules aren't going to do what you want.
In addition they aren't properly supported in newer code.

they handle
the routes. The only difference is between v4 and v6, 2 x v4 = 1 x v6.
There is a difference in the ACL TCAM but it mainly effects IPv6 ACLs.

I believe amazon ran into this not too long ago.
At 768k you are effectively limiting your IPv6 table to 128k (you can't really
go more than that if you expect to use IPv6).
I recommend a 640k/192k split.
As for an article:

I wouldn't say it is good news.
Lots of people smoke and drink too, it doesn't make it healthy.

This is very common practice and practically everyone does it.
Usually if you have your own backbone you enlarge the backbone packet size
though.
Sometimes that isn't an option due to provider switches in the path.
