Hello all.

We are trying to find a clever, scalable way to police
customer upstream traffic (inbound into PE router from the
CE router) if the destination is to a specific set of
prefixes behind one or more routers.

Matching an ACL that defines destination prefixes is not an
option as the upstream routers present multiple, dynamic
prefixes, rendering this a non-scalable choice.

We could also (re)mark inbound packets from the customer's
CE router and then identify and police them on the upstream
routers. However, we are trying to avoid "touching" packets
on the upstream routers.

We have thought up other methods this could be done in IOS,
but uncertain whether they would supported as any kind of
feature (set).

Is there a clever way of achieving this on the PE router?

All help appreciated.

Cheers,

Mark.
