.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This modules implements the encoding and decoding of the IPv6 Routing Extension Header layer.

.PP
See also \fBNet::Frame::Layer\fR for other attributes and methods.
.SH "ATTRIBUTES"
.IX Header "ATTRIBUTES"
.IP "\fBnextHeader\fR" 4
.IX Item "nextHeader"
Protocol number of the next header after the Routing header.
.IP "\fBhdrExtLen\fR" 4
.IX Item "hdrExtLen"
The length of the Routing header in 8\-byte units, not including the first 8 bytes of the header. For a Routing Type of 0, this value is thus two times the number addresses embedded in the header.
.IP "\fBroutingType\fR" 4
.IX Item "routingType"
This field allows multiple routing types to be defined; at present, the only value used is 0.
.IP "\fBsegmentsLeft\fR" 4
.IX Item "segmentsLeft"
Specifies the number of explicitly-named nodes remaining in the route until the destination.
.IP "\fBreserved\fR" 4
.IX Item "reserved"
Not used; set to zeroes.
.IP "\fBaddresses\fR" 4
.IX Item "addresses"
A set of IPv6 addresses that specify the route to be used.
.PP
The following are inherited attributes. See \fBNet::Frame::Layer\fR for more information.

.IP "\fBnew\fR (hash)" 4
.IX Item "new (hash)"
.PD
Object constructor. You can pass attributes that will overwrite default ones. See \fB\s-1SYNOPSIS\s0\fR for default values.
.IP "\fBcomputeLengths\fR" 4
.IX Item "computeLengths"
Computes \fBhdrExtLen\fR and \fBsegmentsLeft\fR based on number of \fBaddresses\fR.
.IP "\fBcomputeSegmentsLeft\fR (0 | 1)" 4
.IX Item "computeSegmentsLeft (0 | 1)"
Disable (0) or enable (1) automatic computing of \fBsegmentsLeft\fR by the \fBcomputeLengths\fR method.  Default is enabled.
.PP
The following are inherited methods. Some of them may be overridden in this layer, and some others may not be meaningful in this layer. See \fBNet::Frame::Layer\fR for more information.
