2. Configure Switch B:
# Configure a static route to subnet 10.110.0.0/24.
<SwitchB> system-view
[SwitchB] ip route-static 10.110.0.0 24 1.1.2.1
# Configure the IP address of VLAN-interface 10.
[SwitchB] interface vlan-interface 10
[SwitchB-Vlan-interface10] ip address 1.1.2.2 255.255.255.0
3. Configure Switch C:
# Configure a static route to subnet 10.110.0.0/24.
<SwitchC> system-view
[SwitchC] ip route-static 10.110.0.0 24 1.1.3.1
# Configure the IP address of VLAN-interface 20.
[SwitchC] interface vlan-interface 20
[SwitchC-Vlan-interface20] ip address 1.1.3.2 255.255.255.0
Verifying the configuration
# Configure the IP address 10.110.0.20/24 for Host A, and specify its gateway address as 10.110.0.10.
# On Host A, Telnet to Switch B that is directly connected to Switch A. The operation succeeds.
# On Host A, Telnet to Switch C that is directly connected to Switch A. The operation fails.
# Ping Switch C from Host A. The operation succeeds.
Telnet uses TCP and ping uses ICMP. The preceding results show that all TCP packets arriving on
VLAN-interface 11 of Switch A are forwarded to next hop 1.1.2.2, and other packets are forwarded
through VLAN-interface 20. The interface PBR configuration is effective.
