Configuration procedure
1. Configure the IP address and subnet mask for each interface as per Figure 32. (Details not shown.)
2. Configure an IPv4 over IPv4 tunnel:
# Create service loopback group 1 on Switch A and specify its service type as Tunnel.
<SwitchA> system-view
[SwitchA] service-loopback group 1 type tunnel
# Disable STP, LLDP and NDP on interface GigabitEthernet 1/0/3 of Switch A, and add the
interface to service loopback group 1. GigabitEthernet 1/0/3 does not belong to VLAN 100 or
VLAN 101.
[SwitchA] interface gigabitethernet 1/0/3
[SwitchA-GigabitEthernet1/0/3] undo stp enable
[SwitchA-GigabitEthernet1/0/3] undo ndp enable
[SwitchA-GigabitEthernet1/0/3] undo lldp enable
[SwitchA-GigabitEthernet1/0/3] port service-loopback group 1
[SwitchA-GigabitEthernet1/0/3] quit
# Create interface Tunnel 0 on Switch A, assign the IP address and subnet mask to the interface
Tunnel 0, and reference service loopback group 1 on interface Tunnel 0.
[SwitchA] interface tunnel 0
[SwitchA-Tunnel0] ip address 50.1.1.1 24
[SwitchA-Tunnel0] service-loopback-group 1
# Specify the tunnel encapsulation mode as IPv4 over IPv4 and assign the source and destination
addresses to the interface.
[SwitchA-Tunnel0] tunnel-protocol ipv4-ipv4
[SwitchA-Tunnel0] source 20.1.1.1
[SwitchA-Tunnel0] destination 30.1.1.2
[SwitchA-Tunnel0] quit
# Create service loopback group 1 on Switch C and specify its service type as Tunnel.
<SwitchC> system-view
[SwitchC] service-loopback group 1 type tunnel
