Configure the route map as follows:
ProCurve(config)# route-map RealTime 10
ProCurve(config-route-map)# match ip precedence 5
ProCurve(config-route-map)# set interface ppp 1
ProCurve(config-route-map)# set ip dscp ef
ProCurve(config-route-map)# set ip df
ProCurve(config-route-map)# exit
ProCurve(config)# interface eth 0/1
ProCurve(config-eth 0/1)# ip policy route-map RealTime
Troubleshooting Routing
When you receive reports that traffic is not reaching its destination, first
attempt to ping the destination from the router to verify that a host or other
network node is not the root of the problem. If the ping confirms that the router
cannot reach the destination, next view the routing table. It should have an
entry for the destination. If it does not, then you will have to troubleshoot your
routing method.
Remember that in order for a ping to be successful, the remote endpoint must
know a route back to the source. If the routing table does include a route to
the destination, the problem could be that the local router is not advertising
correct routing information to other routers.
The show and debug commands described in the following sections are
enable mode commands. However, you can also enter the commands from
configuration mode contexts by adding the do option.

Monitoring the Routing Table

To view the routing table, enter this enable mode command:
ProCurve# show ip route
