Enabling EVI on transport-facing physical
An EVI tunnel can provide services
for only one EVI network.
An extended VLAN can be
assigned to only one EVI network.
(Optional.)
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 EVI ARP flood suppression
Perform this task to reduce ARP
request broadcasts on an EVI
network.
(Optional.)
Enabling EVI flooding for all destination-unknown frames
Perform this task to flood frames
with unknown MAC addresses to
the EVI tunnel interface.
(Optional.)
Enabling selective flooding for a MAC address
Perform this task for special
multicast MAC addresses that
require Layer 2 inter-site
forwarding but cannot be learned
into the MAC address table.
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 uniquely identify the sites in an EVI network, you can change their site IDs. To avoid site ID conflict,
follow these guidelines when you configure site IDs:
•
An edge device can use the default or manually assigned site ID. Site conflict does not occur if
the edge devices at different sites all use the default site ID.
•
Manually assigned site IDs must be unique among sites.
When the site IDs of two devices conflict, 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.
