Marking Packets

Hi

How is it possible to mark packets in one router and define its actions ( based on marked Packets ) in another Router ?


Thanks in advance.

no. packet-marks are only within one router. When packet leaves the router, all marks are removed.

Hi
Thanks for your reply.

I will tell you what I am up to , then you may suggest some possible work around.

I am setting a hotspot with external AAA . As we know authentication ( with the help of AAA ) as well as bandwidth restriction is performed by the hotspot itself. I wanted to segregate these two jobs ,i.e.- hotspot will only do the authentication. For bandwidth restriction , it will just somehow mark packets which will be recognised by some upstream router and implement qos based on that marking. I use the term marking as a generic term.

Is there any way to acheive it ?

if you are not using NAT on the hotspot then you can easily distinguish what packets are coming from where, and if you have to do NAT, do that after QoS (on same router).

Hi
I am not using NAT anywhere in the whole setup , rather deliberately avoided it.

I can easily categorize any traffic coming into the hotspot since that is the first L3 componenet where the user-traffic is coming to , but just got struck how to propagate that categorization to any router sitting upstream.
