Single-homed EVI network configuration example
Network requirements
As shown in Figure 8 , use EVI to connect site 1, site 2, and site 3 across an IP network into a large Layer
2 network, and extend VLAN 21 to VLAN 100 across the sites.
Use network ID 1 to identify the EVI network.
Use Switch A as an ENDS and all other edge switches as ENDCs for neighbor discovery.

Configuration procedure
This example assumes that routes have been configured for the sites to reach each other.
1. Configure Switch A:
# Configure the EVI tunnel source interface (VLAN-interface 10 in this example), and assign the
transport-facing physical interface GigabitEthernet 3/0/1 to the VLAN.
<SwitchA> system-view
[SwitchA] vlan 10
[SwitchA-vlan10] port gigabitethernet 3/0/1
[SwitchA-vlan10] quit
[SwitchA] interface vlan-interface 10
[SwitchA-Vlan-interface10] ip address 1.1.1.1 24
[SwitchA-Vlan-interface10] quit
# Create an IPv4 EVI tunnel interface.
[SwitchA] interface tunnel 0 mode evi
# Set the network ID of the EVI tunnel interface to 1.
[SwitchA-Tunnel0] evi network-id 1
# Specify the IP address of VLAN-interface 10 as the source IP of the EVI tunnel.
[SwitchA-Tunnel0] source 1.1.1.1
# Set the tunnel keepalive interval to 20 seconds and the maximum number of transmissions to 2.
[SwitchA-Tunnel0] keepalive 20 2
