Configuring Policy
Routing Based on Packet
Size
Network requirements
The policy lab1 is applied to the interface Ethernet 1/0 of Router A. Packets with a
size from 64 to 100 bytes are forwarded to 150::2/64, while packets with a size
from 101 to 1,000 bytes are forwarded to 151::2/64. All other packets are
forwarded through the routing table.
