OSPF must send acknowledgment of each newly received LSA (link-state adevertisement). An LSA that is not acknowledged must be retransmitted over and over again until it is acknowledged. The link-state retransmit interval defines the time between retransmissions. To configure the OSPF retransmit interval, use the set protocols ospf4 area interface vif address retransmit-interval command in L2/L3 configuration mode.

Command Syntax

set protocols ospf4 vrf vrf-name area area-id interface interface-name vif vif-name address ip-address retransmit-interval time



Optional. Specifies a VRF name. The value is a string. It’s a user-defined VRF set by the command set ip vrf <vrf-name> [description <string>].

Note that: The configuration is in the default VRF if not explicitly bound to any VRF.

area-idOSPF area identifier.
interface-nameInterface name.
vif-nameVirtual interface name.
ip-addressVirtual interface IP address used for OSPF.
timeOSPF retransmit interval in seconds. The range is 1-65535.


This example sets the OSPF retransmit interval to 20 seconds:

admin@Switch# set protocols ospf4 area interface vlan2 vif vlan2 address retransmit-interval 10
