The interval between OSPFv3 LSA refreshes can be modified.
device# configure terminal
device(config)# ipv6 router ospf
device(config-ipv6-router-ospf-vrf-default-vrf)# timers lsa-group-pacing 120
The following example restores the pacing interval to the default value of 240 seconds (4 minutes).
device# configure terminal device(config)# ipv6 router ospf device(config-ipv6-router-ospf-vrf-default-vrf)# no timers lsa-group-pacing
