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 Command Remarks
1. Enter system view. system-view N/A
2. Enter EVI tunnel interface
view. interface tunnel number [ mode
evi ]
N/A
3. Configure the minimum LSP
transmit interval and the
maximum number of LSP
segments sent at each
interval.
evi isis timer lsp time [ count
count ]
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.
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 Command Remarks
1. Enter system view. system-view N/A
2. Enter EVI IS-IS process view. evi-isis process-id N/A
3. Configure the maximum LSP
lifetime.
timer lsp-max-age seconds
The default maximum LSP lifetime is
1200 seconds.
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 Command Remarks
1. Enter system view. system-view N/A
2. Enter EVI IS-IS process
view.
evi-isis process-id N/A
3. Configure the LSP
refresh interval.
timer lsp-refresh seconds
The default LSP refresh interval is 900 seconds.
The minimum LSP transmit interval and the maximum
number of LSPs sent at each interval can affect the
actual LSP refresh interval.
To avoid unnecessary age-outs, appropriately set
the LSP refresh interval and the LSP lifetime.
