I have to implement qos and this is what i am planning to do.
My branch to RO link is 64kbps,Ro to MPLs 2Mbps,MPLS to DC 20Mbps
I have to main traffic classes.
1.IPSEC traffic encrypted from Branch to firewall.
2.Critical traffic from Branch to DC.
On my Branch router (1700) i am marking ipsec traffic at input interface and setting it to ip precedence of 4.
on the output intrface i am matching the ip precedence of 4 and assgining it bandwidth of 35%
For the second traffic i am matching it with ip address and assgining it bandwidth of 35%
Since the first class is ipsec i have to do the marking on branch itself so the i could implement qos for ipsec.
On the RO at output interface i am matching ip precedence of 5 assgining it bandwidth of 35% for ipsec
and for the other class i am matching the traffic setting the precedence to 4 and assgining it bandwidth of 35% for ipsec .
My provider is ready to make the chages in his network for my qos to work .
SO in my sending precedence value of 4 and 5 for him to match and send to my DC.
My DC router is 7600 with sup 32 so i cannot apply bandwidth command there .
This is where i have some doubt.
since i have 1 PQ for input and output on 7600 what is the best way to put QOS there.
