• Perform network optimization tasks (see " Optimizing an EVI IS-IS network ") except configuring the
EVI IS-IS hello interval and the maximum LSP lifetime.
The ID of an automatically created process is the same as the EVI tunnel interface number.
Alternatively, you can use the evi-isis command to create an EVI IS-IS process manually.
To delete a manually created EVI IS-IS process, you must use the undo evi-isis command.
• If EVI IS-IS settings exist on the EVI tunnel interface, the undo evi-isis command only deletes settings
configured in EVI IS-IS process view.
• If no EVI IS-IS settings exist on the EVI tunnel interface, the undo evi-isis command deletes both the
EVI IS-IS process and all settings configured in EVI IS-IS process view.
An automatically created EVI IS-IS process is automatically deleted when you delete all EVI IS-IS settings
from the EVI tunnel interface.
To create an EVI IS-IS process or enter its view:
Step Command Remarks
1. Enter system view. system-view N/A
2. Create an EVI IS-IS
process or enter EVI IS-IS
process view.
evi-isis process-id
By default, no EVI IS-IS process is configured.
The process ID you specify must be the same as
the EVI tunnel interface number.
The EVI IS-IS process takes effect after you
configure extended VLANs on the tunnel
interface.
Optimizing an EVI IS-IS network
Perform the tasks in this section to optimize an EVI IS-IS network for bandwidth efficiency and high
performance.
Configuring the EVI IS-IS hello interval
EVI edge devices send EVI IS-IS hellos over EVI links to establish and maintain adjacencies and elect the
inter-site DED on each EVI link.
A short interval increases the speed of network convergence but requires more system resources.
NOTE:
The hello interval of a DED is one-third of the hello interval set with the evi isis timer hello command.
To configure the EVI IS-IS hello interval on an EVI tunnel interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter EVI tunnel interface
view. interface tunnel number [ mode
