The Text field is one or more octets, and its contents are
implementation dependent. The field is not NUL (hex 00)
terminated. It is intended to be human readable and MUST NOT
affect operation of the protocol.
For IPv6 routes, it SHOULD contain a destination prefix optionally
followed by a slash and a decimal length specifier stating how
many high order bits of the prefix to use. That is followed by a
space, a gateway address, a space, and one or more metrics
(encoded in decimal) separated by spaces. Prefixes and addresses
are formatted as described in . For example,
"2000:0:0:106::/64 2000::106:a00:20ff:fe99:a998 1".Whenever the gateway address is the IPv6 unspecified address the
IP address of the user SHOULD be used as the gateway address. The
unspecified address can be expressed in any of the acceptable
formats described in . For example, "2000:0:0:106::/64 :: 1".
