Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text. Not only this slows down the mdoc(7) processing significantly, but it also has an undesired (in this case) effect of disabling hyphenation within the entire enclosed block.

.Sh DESCRIPTION
|
|
The
|
|
.Nm

|
command manipulates the address mapping table
|
|
used by Neighbor Discovery Protocol (NDP).
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Dump the currently existing NDP entries.
|
|
.It Fl A Ar wait
|
|
Repeat
|
|
.Fl a
|
|
(dump NDP entries)
|
|
every
|
|
.Ar wait
|
|
seconds.
|
|
.It Fl c
|
|
Erase all the NDP entries.
|
|
.It Fl d
|
|
Delete specified NDP entry.
|
|
.It Fl f
|
|
Parse the file specified by
|
|
.Ar filename .
|
|
.It Fl H
|
|
Harmonize consistency between the routing table and the default router
|
|
list; install the top entry of the list into the kernel routing table.
|
|
.It Fl I Op Cm delete | Ar interface
|
|
Shows or specifies the default interface used as the default route when
|
|
there is no default router.
|
|
If no argument is given to the option,
|
|
the current default interface will be shown.
|
|
If an
|
|
.Ar interface
|
|
is specified, the interface will be used as the default.
|
|
If a special keyword
|
|
.Ic delete
|
|
is specified, the current default interface will be deleted from the kernel.
|
|
.It Fl i Ar interface Op Ar flags...
|
|
View ND information for the specified interface.
|
|
If additional arguments
|
|
.Ar flags
|
|
are given,
|
|
.Nm
|
|
sets or clears the specified flags for the interface.
|
|
Possible flags are as follows.
|
|
All of the flags can begin with the
|
|
special character
|
|
.Ql - ,
|
|
which means the flag should be cleared.

interface.
|
|
NUD is usually turned on by default.
|
|
.El
|
|
.It Fl n
|
|
Do not try to resolve numeric address to hostname.

.Li temp
|
|
is given in the command.

|
.Li proxy
