Virtual Destination Ports
RFC 2207 describes a set of virtual destination ports for use with
IPSEC.
The range of possible vDstPort values is broken down into sections,
in a fashion similar to the UDP/TCP port ranges.
0 Illegal Value
1 - 10 Reserved. Contact authors.
11 - 8191 Assigned by IANA
8192 - 65535 Dynamic
IANA is directed to assign the well-known vDstPorts using the
following criteria: Anyone who asks for an assigned vDstPort must
provide a) a Point of Contact, b) a brief description of intended
use, and c) a short name to be associated with the assignment (e.g.
"ftp").
None are currently assigned.
---------------------------------------------------------------------
Error Codes and Globally-Defined Error Value Sub-Codes
An Error Code is an 8-bit quantity that appears in an ERROR_SPEC
object to broadly define an error condition. With each Error Code
there may be a 16-bit Error Value that further specifies the cause
of the error. Error Values may be globally defined, in which case
the sub-code component is assigned by IANA [RFC2205].
The following list extends the basic list of Error Codes and Values that
are defined in [RFC2205].
Error Code Meaning
24 Routing Problem [LSP-TUN]
This Error Code has the following globally-defined Error
Value sub-codes:
1= Bad EXPLICIT_ROUTE object [LSP-TUN]
2= Bad strict node [LSP-TUN]
3= Bad loose node [LSP-TUN]
4= Bad initial subobject [LSP-TUN]
5= No route available toward [LSP-TUN]
destination
6= Unacceptable label value [LSP-TUN]
7= RRO indicated routing loops [LSP-TUN]
8= MPLS being negotiated, but a [LSP-TUN]
non-RSVP-capable router stands
in the path
9= MPLS label allocation failure [LSP-TUN]
10= Unsupported L3PID [LSP-TUN]
25 Notify Error [LSP-TUN]
This Error Code has the following globally-defined Error
Value sub-codes:
1= RRO too large for MTU [LSP-TUN]
2= RRO Notification [LSP-TUN]
26 NEW-AGGREGATE-NEEDED [RFCXXXX]
---------------------------------------------------------------------
Miscellaneous Definitions
Sub-objects of the EXPLICIT_ROUTE object with C-Type = 1: [LSP-TUN]
0 Reserved [LSP-TUN]
1 IPv4 prefix [LSP-TUN]
2 IPv6 prefix [LSP-TUN]
32 Autonomous system number [LSP-TUN]
Sub-objects of the RECORD_ROUTE object with C-Type = 1: [LSP-TUN]
0 Reserved [LSP-TUN]
1 IPv4 address [LSP-TUN]
2 IPv6 address [LSP-TUN]
