Edge devices send their adjacency hold time in hello packets to update the adjacencies with their
neighbors. An edge device removes the adjacency with a neighbor if it does not receive a hello packet
from the neighbor before the timer expires.
To configure the multiplier for calculating the adjacency hold time 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
evi ]
N/A
3.
Configure the multiplier for
calculating the adjacency
hold time.
evi isis timer holding-multiplier
value
The default multiplier is 3.
The maximum adjacency hold time is
65535 seconds. If this value is
exceeded, the actual adjacency hold
time is set to 65535 seconds.
Configuring the DED priority
The edge devices on an EVI link exchange their DED priority in EVI IS-IS hello packets to elect a DED for
periodic LSDB synchronization. You can use the evi isis timer csnp command to change the
synchronization interval.
The edge device with higher DED priority is more likely to be elected as the DED. If two edge devices
have the same DED priority, the device with the highest MAC address is elected.
To configure the DED priority of the edge device 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
evi ]
N/A
3.
Configure the DED priority.
evi isis ded-priority value
The default DED priority is 64.
Configuring the CSNP packet transmit 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 transmit 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
transmit interval.
evi isis timer csnp seconds
By default, a DED sends CSNP
packets every 10 seconds.
