• EVB and EVI cannot work together. Do not configure both features on an interface. For more
information about EVB, see EVB Configuration Guide.
• If the link type of a site-facing interface is access, it can receive only tagged packets from the VLAN
to which the port has been assigned.
• Spanning tree protocols are not supported on site-facing interfaces that are assigned to extended
VLANs. Make sure the interfaces do not form loops with other devices.
EVI configuration task list
Perform the following tasks on all edge devices of an EVI network:
Tasks at a glance Remarks
Configuring EVI basic features :
• (Optional.) Configuring a site ID
• (Required.) Configuring an EVI tunnel :
{
(Required.) Assigning a network ID to the EVI tunnel
{
(Required.) Specifying extended VLANs on the EVI tunnel
{
(Required.) Configuring ENDP
{
(Required.) Enabling EVI on transport-facing physical
interfaces
An EVI tunnel can provide services for
only one EVI network.
An extended VLAN can be assigned only
to one EVI network.
(Optional.) Tuning EVI IS-IS parameters
EVI IS-IS automatically runs on an EVI
tunnel interface immediately after the
interface is created.
You can tune EVI IS-IS parameters for
optimizing network performance.
(Optional.) Enabling selective flood for a MAC address
Perform this task for multicast MAC
addresses or unknown unicast addresses
that require Layer 2 inter-site forwarding.
Configuring EVI basic features
All tasks in this section are required for setting up an EVI network.
Configuring a site ID
By default, all edge devices in an EVI network have a site ID of 0. To identify the site of each edge device,
you can change their site IDs.
Manually assigned site IDs must be unique in the EVI network. If the edge devices at two sites are
assigned the same site ID, EVI IS-IS isolates the device with the lower MAC address. The isolated device
can only receive EVI IS-IS hello packets. It cannot exchange EVI IS-IS packets with other neighbors. To
identify isolated devices, use the display evi isis brief command or the display evi isis peer command.
NOTE:
EVI IS-IS does not perform isolation for edge devices that use the default site ID.
