Configuring the CSNP packet sending interval
This configuration takes effect only on DEDs.
The DEDs in an EVI network regularly send CSNP packets to advertise LSP summaries for LSDB
synchronization.
To configure the CSNP packet sending interval on a DED:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter tunnel interface view.
interface tunnel number
[ mode evi ]
N/A
3. Configure the CSNP packet
sending interval.
evi isis timer csnp seconds
By default, a DED sends CSNP
packets every 10 seconds.
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
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.
