EVI configuration examples

Single-homed EVI network configuration example

Network requirements

As shown in Figure 7.

• Use EVI to extend VLANs 21 through 100 across site 1, site 2, and site 3 over an IPv4 network.

• 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.

• Configure a routing policy on Switch A to advertise MAC addresses in VLANs 21 to 90 to the

remote sites.

<SwitchA> system-view

[SwitchA] evi site-id 1

# Configure the EVI tunnel source interface (VLAN-interface 10 in this example), and assign

transport-facing physical interface GigabitEthernet 1/0/1 to the VLAN.

[SwitchA] vlan 10

[SwitchA-vlan10] port gigabitethernet 1/0/1

[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.
