Configuring the minimum LSP sending interval and the maximum number of LSPs sent at each interval
When MAC reachability information changes, an edge device sends LSP updates to notify its adjacent
EVI neighbors.
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
sending interval and the maximum
number of LSP segments sent at
each interval.
evi-isis timer lsp time [ count
count ]
By default, the minimum LSP
sending interval is 100
milliseconds, and a maximum of
five LSP segments can be sent at
each interval.
Before the minimum sending
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
it 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
An edge device regularly sends LSP updates to remote edge devices for updating 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
