<H2>DESCRIPTION</H2>
<I>Spigrp</I>
groups IPSEC Security Associations (SAs) together or ungroups
previously grouped SAs.
An entry in the IPSEC extended
routing table can only point
(via a destination address, a Security Parameters Index (SPI) and
a protocol identifier) to one SA.
If more than one transform must be applied to a given type of packet,
this can be accomplished by setting up several SAs
with the same destination address but potentially different SPIs and protocols,
and grouping them with
<I>spigrp</I>.
<P>
The SAs to be grouped,
specified by destination address (DNS name lookup, IPv4 dotted quad or IPv6 coloned hex), SPI
('0x'-prefixed hexadecimal number) and protocol ("ah", "esp", "comp" or "tun"),
are listed from the inside transform to the
outside;
in other words, the transforms are applied in
the order of the command line and removed in the reverse
order.
The resulting SA group is referred to by its first SA (by
<I>af1</I>,
<I>dst1</I>,
<I>spi1</I>
and
<I>proto1</I>).
<P>
The --said option indicates that the SA IDs are to be specified as
one argument each, in the format <proto><af><spi>@<dest>. The SA IDs must
all be specified as separate parameters without the --said option or
all as monolithic parameters after the --said option.
<P>
The SAs must already exist and must not already
be part of a group.
<P>
If
<I>spigrp</I>
is invoked with only one SA specification,
it ungroups the previously-grouped set of SAs containing
the SA specified.
<P>
The --label option identifies all responses from that command
invocation with a user-supplied label, provided as an argument to the
label option. This can be helpful for debugging one invocation of the
command out of a large number.
<P>
The command form with no additional arguments lists the contents of
/proc/net/ipsec_spigrp. The format of /proc/net/ipsec_spigrp is
discussed in <A HREF="ipsec_spigrp.5.html">ipsec_spigrp</A>(5).

<H2>BUGS</H2>
Yes, it really is limited to a maximum of four SAs,
although admittedly it's hard to see why you would need more.
