3 Modify the next hop for the packets from PC1.

Define the next hop for the packets from PC1 as 2.0.0.1.

Modify the correspondence between 802.1p priority levels and local priority levels 
to change the mapping between 802.1p priority levels and queues so that packets 
are put into outbound queues according to the new mapping. Use WRR algorithm 
for the queues 0 to 5 at the port GE7/1/1. Set the queues 0, 1 and 2 into WRR 
queue 1, with weight respectively as 20, 20 and 30; set the queues 3, 4 and 5 into 
WRR queue 2, with weight respectively as 20, 20 and 40. The queues 6 and 7 use 
the SP algorithm. See Queue Scheduling for the default mapping.

2 Use the WRR algorithm for the queues 0 to 5. Set the queues 0, 1 and 2 into WRR 

queue 1, with weight respectively as 20, 20 and 30; set the queues 3, 4 and 5 into 
WRR queue 2, with weight respectively as 20, 20 and 40. Use SP algorithm for the 
queues 6 and 7.
