Verifying the configuration
After you complete the configuration, verify that when PE 2 receives packets of VPN 1, it forwards the
packets to Switch A instead of CE 2.
GRE tunnel end packets policy routing configuration example
Network requirements
As shown in Figure 129 , Switch A and Switch B are connected over the Internet. Group 1 and Group 2
are two private networks interconnected through a GRE tunnel configured on two switches. Configure a
QoS policy on Switch B to redirect packets destined for 201.1.1.2 to the next hop 202.1.1.2.
