Multiple-EVI-networks configuration example
Network requirements
Use EVI to connect the sites of the data center in Figure 9 . To isolate different types of traffic and extend
their VLANs to different sites, set up the following EVI networks:
• Database EVI network (network ID 1)—Extends VLANs 100 and 101 across sites 2, 3, and 4.
• Network management EVI network (network ID 2)—Extends VLAN 4000 across all the sites.
• Web service EVI network (network ID 3)—Extends VLANs 50 to 80 across sites 1 and 4.
In each EVI network, use the edge device at site 4 as an ENDS and all other edge devices as its ENDCs.

Configuration procedure
This example assumes that routes have been configured for the sites to reach each other.
1. Configure site 4:
# Configure the EVI tunnel source interface for all EVI tunnels (VLAN-interface 10 in this example),
and assign the transport-facing physical interface GigabitEthernet 3/0/1 to the VLAN.

[Site4] vlan 10

# Configure the database EVI network.
