Title: Removing a Restriction on the use of MPLS Explicit NULL
State: Pending
Authors: Eric Rosen
Group: Multiprotocol Label Switching (mpls)
Date: 2004-04-23
The label stack encoding for MPLS (Multi-protocol Label Switching) defines
a reserved label value known as "IPv4 Explicit NULL" and a reserved label
value known as "IPv6 Explicit NULL". Previously, these labels were only
legal when they occurred at the bottom of the MPLS label stack. This
restriction is now removed, so that these label values may legally occur
anywhere in the stack.
