here is my scenario:
host(a)-------------------eo--router(1)--s1-------2mbps-----------so-router(
2)--s1---2mbps-------s1--router(3)-------eo---host(b)

-----------------64k-------------------so---router(4)--s1---------64k-------
--i have a voice application, and a specific data application on host(a) that talks to host(b) i need to implement qos here. i choose differential method
what did i do?
a) i defined an access-list on route1, router 3 to classify all voice traffic (acl -voice) and all data traffic(acl-filer), all other traffic is default b) i define a class map in both routers where i allocate 64k for voice, 100k for filer(data), and the rest for other traffic
i need to keep this allocation strict so i use priority and police under class-map, allocating priority 64k for class-voice and priority 100k for data.
c) i define a policy called voice-data, where i do shaping allocating 64k+100k for the service. i apply this policy to router1:s1, router2:s0, router2:s1, router3:s1.
because the data might travel through r4 when the link2/router2 fails. i also apply this service policy to router4:s0 and router4:s1
d) on the incoming interfaces on r1 (e0) and r3(e0) i apply a CAR (or another policy-map to set the dscp/tos) to identify the voice and filer traffic and assign a tag/dscp. i use this tag assigned in the boundry to drive the traffic across my network my making all my router aware of this qos need.
will this work? else, what is missing.
is there a page on the web, where one of such scenario is explained with configs.(all possible options and queues) ??
thanks, sen
