Technical Summary
The LDP specification [RFC5036] for the Wildcard FEC element has
several deficiencies. This document corrects those deficiencies. In
addition, it specifies the Typed Wildcard FEC for the Prefix FEC
Element Type defined in RFC5036.
The RFC5036 specification of the Wildcard FEC Element has the
following deficiencies which limit its utility:
1) The Wildcard FEC Element is untyped. There are situations where
it would be useful to be able to refer to all FECs of a given
type.
2) Use of the Wildcard FEC Element is limited to Label Withdraw and
Label Release messages only. There are situations where it would
be useful in Label Request messages.
This document:
- Addresses the above deficiencies by defining a Typed Wildcard
FEC Element and procedures for its use.
- Specifies use of the LDP capability mechanism [RFC5561] at
session establishment time for informing a peer that an LDP
speaker is capable of handling the Typed Wildcast FEC.
- Specifies the Typed Wildcard FEC Element for the Prefix FEC
Element specified by RFC5036.
Note that this document does not change procedures specified for the
LDP Wildcard FEC Element by RFC5036.
