default: 0
description: Configures sysctl net.ipv6.{default/all}.disable_ipv6 keys

type: number
NeighbourGcThreshold1:
default: 1024
description: Configures sysctl net.ipv4.neigh.default.gc_thresh1 value.
This is the minimum number of entries to keep in the ARP
cache. The garbage collector will not run if there are
fewer than this number of entries in the cache.
type: number
NeighbourGcThreshold2:
default: 2048
description: Configures sysctl net.ipv4.neigh.default.gc_thresh2 value.
This is the soft maximum number of entries to keep in the
ARP cache. The garbage collector will allow the number of
entries to exceed this for 5 seconds before collection will
be performed.
type: number
NeighbourGcThreshold3:
default: 4096
description: Configures sysctl net.ipv4.neigh.default.gc_thresh3 value.
This is the hard maximum number of entries to keep in the
ARP cache. The garbage collector will always run if there
are more than this number of entries in the cache.
