I am wondering if this can be flushed when a new record is learned after the timeout period. ?
can you try to restart bigd? i may be wrong but i think bigip will resolve fqdn node when bigd is restarted.
restart bigd
[root@ve11c:Active:In Sync] config tmsh list ltm node google
ltm node google {
fqdn {
autopopulate enabled
name www.google.com
}
state fqdn-up
}
[root@ve11c:Active:In Sync] config date; tmsh restart sys service bigd
