Step
3. Configure the CSNP transmit
interval.
Configuring the minimum LSP transmit interval and the maximum number of LSPs sent at
each interval
The edge device generates an LSP update when any LSDB content changes. For example, an LSP
update is generated when a MAC address is removed or added.
To control EVI IS-IS LSP traffic on the EVI network:
Step
1. Enter system view.
2. Enter EVI tunnel interface
view.
3. Configure the minimum LSP
transmit interval and the
maximum number of LSP
segments sent at each
interval.
Configuring the maximum LSP lifetime
EVI edge devices add a lifetime in each LSP they have advertised, and update LSPs regularly or
when MAC reachability information changes. If an edge device does not receive an update for an
LSP before the lifetime expires, the edge device removes the LSP from the LSDB and removes the
MAC addresses advertised through the LSP from the data plane.
To specify the maximum lifetime of the LSPs generated by an EVI IS-IS process:
Step
1. Enter system view.
2. Enter EVI IS-IS process
view.
3. Configure the maximum LSP
lifetime.
Configuring the LSP refresh interval
The edge device sends LSP updates at the refresh interval to update MAC reachability information.
To change the LSP refresh interval:
Step
1. Enter system view.
2. Enter EVI IS-IS
process view.
3. Configure the LSP
refresh interval.

Remarks
By default, a DED sends CSNP
packets every 10 seconds.

By default, the minimum LSP
transmit interval is 100
milliseconds, and a maximum of
five LSP segments can be sent at
each interval.
Before the minimum transmit
interval is reached, the EVI tunnel
interface cannot send LSP
segments.
