[c-nsp] Limiting BW in an HSRP set-up

[Vincent De Keyzer]

Hello list,

 

please consider the following scenario :

*	typical datacenter with two routers running HSRP 
*	datacenter customer with 2 servers, each being connected on one
dedicated (managed) ethernet port 

 

How do I limit bandwidth for this customer?

 

I can easily limit upstream traffic, as the customer will probably use the
HSRP address as a default GW; hence I can rate-limit on the .1q subinterface
input.

 

But what about downstream traffic? I have the feeling that all I can do is
to traffic-shape (or rate-limit) output on both .1q subinterfaces, but
customer might then theoretically use twice the bandwidth he is paying for?
