Line 1061 tunnel interface.

The maximum time-to-live (hop count) value for an IPv4 packet generated by

.Xr gre 4

tunnel interface.

.It Li ip.hashsize

The size of IPv4 Fast Forward hash table.

This value must be a power of 2 (64, 256...).

A larger hash table size results in fewer collisions.

.It Li ip6.hdrnestlimit

The number of IPv6 extension headers permitted on incoming IPv6 packets.

If set to 0, the node will accept as many extension headers as possible.

.It Li ip6.hashsize

The size of IPv6 Fast Forward hash table.

This value must be a power of 2 (64, 256...).

A larger hash table size results in fewer collisions.

Also see

.Li ip6.maxflows .

.It Li ip6.hlim

The default hop limit value for an IPv6 unicast packet sourced by the node.

This value applies to all the transport protocols on top of IPv6.

Line 1391 IPv6 Fast Forwarding is enabled by defau

Line 1406 IPv6 Fast Forwarding is enabled by defau

If set to 0, IPv6 Fast Forwarding is disabled.

.Li ip6.maxflows

controls the maximum amount of flows which can be created.

The default value is 256.

.It Li ip6.maxfragpackets

The maximum number of fragmented packets the node will accept.

0 means that the node will not accept any fragmented packets.

Line 1405 The flag is provided basically for avoid

Line 1421 The flag is provided basically for avoid

If set to 1, ICMPv6 redirects may be sent by the node.

This option is ignored unless the node is routing IP packets,

and should normally be enabled on all systems.

.It Li ip6.rht0

This variable controls processing of routing header type 0 packets. The

possible values are:

.Bl -tag -width "-1"

.It Li \-1

Processing is disabled (default).

.It Li 0

Processing is enabled only for routers and not for hosts.

.It Li 1

Processing is enabled for both routers and hosts.

.El

.It Li ip6.rr_prune

The variable specifies interval between IPv6 router renumbering prefix

babysitting, in seconds.
