假设我想使用:
$ ip ntable show dev eth0
inet arp_cache
dev eth0
refcnt 4 reachable 20744 base_reachable 30000 retrans 1000
gc_stale 60000 delay_probe 5000 queue 31
app_probes 0 ucast_probes 3 mcast_probes 3
anycast_delay 1000 proxy_delay 800 proxy_queue 64 locktime 1000
inet6 ndisc_cache
dev eth0
refcnt 1 reachable 40768 base_reachable 30000 retrans 1000
gc_stale 60000 delay_probe 5000 queue 31
app_probes 0 ucast_probes 3 mcast_probes 3
anycast_delay 1000 proxy_delay 800 proxy_queue 64 locktime 0
什么是ndisc_cache
?
