Configuration procedure
Configure Switch A:
1.
# Configure GigabitEthernet 3/0/1 to operate in Layer 3 mode.
<SwitchA> system-view
[SwitchA] interface GigabitEthernet 3/0/1
[SwitchA-GigabitEthernet3/0/1] port link-mode route
# Configure the IP address of GigabitEthernet 3/0/1.
[SwitchA-GigabitEthernet3/0/1] ip address 10.1.1.1 24
[SwitchA-GigabitEthernet3/0/1] quit
# Configure DHCP.
[SwitchA] dhcp enable
[SwitchA] dhcp server ip-pool 1
[SwitchA-dhcp-pool-1] network 10.10.1.0 mask 255.255.255.0
[SwitchA-dhcp-pool-1] gateway-list 10.10.1.1
[SwitchA-dhcp-pool-1] quit
[SwitchA] ip route-static 10.10.1.0 24 10.1.1.2
Configure Switch B:
2.
# Enable DHCP.
<SwitchB> system-view
[SwitchB] dhcp enable
# Configure GigabitEthernet 3/0/1 to operate in Layer 3 mode.
[SwitchB] interface GigabitEthernet 3/0/1
[SwitchB-GigabitEthernet3/0/1] port link-mode route
# Configure the IP addresses of GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2.
[SwitchB-GigabitEthernet3/0/1] ip address 10.1.1.2 24
