Step Command Remarks
2. Enter Layer 2 or Layer 3
Ethernet interface view. interface interface-type
interface-number
N/A
3. Enable EVI on the interface. evi enable
By default, EVI function is disabled
on all interfaces.
Tuning EVI IS-IS parameters
EVI IS-IS automatically runs on an EVI link immediately after the link is set up. You can tune EVI IS-IS
parameters to optimize the protocol performance.
EVI IS-IS configuration task list
All EVI IS-IS configuration tasks are optional.
Tasks at a glance Remarks
Configuring an EVI IS-IS process N/A
Optimizing an EVI IS-IS network :
• Configuring the EVI IS-IS hello interval
• Configuring the hello multiplier for calculating the
adjacency hold time
• Configuring the DED priority
• Configuring the CSNP packet sending interval
• Configuring the minimum LSP sending interval and the
maximum number of LSPs sent at each interval
• Configuring the maximum LSP lifetime
• Configuring the LSP refresh interval
• Enabling adjacency change logging
Perform the EVI IS-IS network optimization tasks
to enable fast EVI link failure detection, set
appropriate MAC reachability information
update interval, and control the volume of LSP
and CSNP traffic on an EVI network.
Configuring graceful restart for an EVI IS-IS process Perform this task for providing nonstop services.
Increasing the maximum number of MAC entries in an LSP
for an EVI IS-IS process Perform this task depending on the MAC
address table size on the edge device.
Configuring an EVI IS-IS process
When you create an EVI tunnel interface, the system automatically creates an EVI IS-IS process that has
the same number as the interface. You can access the EVI IS-IS process view to change EVI IS-IS
process-specific settings.
Alternatively, you can create an EVI IS-IS process before creating an EVI tunnel interface and configure
the process-specific settings, but the process and its settings take effect only after the interface is created.
An automatically created EVI IS-IS process can be manually deleted by using the undo evi-isis command
or automatically deleted when you delete its EVI tunnel interface. In contrast, to delete a manually
created EVI IS-IS process, you must use the undo evi-isis command. Deleting its EVI tunnel interface can
only invalidate the process.
