Hi all,
I have the requirement of DSCP marking EIGRP traffic from CS6 to AF31. I tried to use local-policy routing as per the following:
!
ip access-l extended EIGRP
permit eigrp any any
!
route-map LOCAL
match ip address EIGRP
set iop TOS|DSCP
!
ip local policy route-map LOCAL
!
The problem is that I don't have the option of setting DSCP marking in the route-map. Setting the precedence doesn't help in my case and the TOS option doen't reflect the TOS field of the IP header. Following is an extract from the documentation for using 'set ip tos'

Usage Guidelines
This command allows you to set four bits in the ToS byte header. Table 35 shows the format of the four bits in binary form.
Table 35 ToS Bits and Description
T3 | T2 | T1 | T0 | Description |
0 | 0 | 0 | 0 | 0 normal forwarding |
0 | 0 | 0 | 1 | 1 minimum monetary cost |
0 | 0 | 1 | 0 | 2 maximum reliability |
0 | 1 | 0 | 0 | 4 maximum throughput |
1 | 0 | 0 | 0 | 8 minimum delay |
The T3 bit sets the delay. Setting T3 to 0 equals normal delay, and setting it to 1 equals low delay.
The T2 bit sets the throughput. Setting this bit to 0 equals normal throughput, and setting it to 1 equals maximum throughput. Similarly, the T1 and T0 bits set reliability and cost, respectively. Therefore, as an example, if you want to set a packet with the following requirements:
minimum delay T3 = 1
normal throughput T2 = 0
normal reliability T1 = 0
minimum monetary cost T0 = 1

Using COPP doesn't allow as well setting the QOS marking.
Any suggestions or other options for DSCP marking EIGRP traffic.
Thanks,
Jad
