This command flushes all the entries in the prefix list and forces a re-run= of SLAAC on the interface, immediately removing obsolete IPv6 addresses and triggering reconfiguration from Router Advertisements. To automate this, a = cron job can periodically run a simple connectivity test (for example a ping to a known IPv6 endpoint) and, if it does not complete within a reasonable time, execute ndp -P . This avoids long periods with unreachable but still-va= lid addresses, although it requires manual or scripted execution and does not replace proper honoring of pltime/vltime settings in rtadvd. --=20 You are receiving this mail because: You are the assignee for the bug.=
