TITLE : IMPLEMENTING EXTENSIONS TO WIRESHARK TO SUPPORT DECODING OF MPLS-TP
PAYLOADS
Source draft used : MPLS WORKING GROUP-IETF, Proactive Connectivity
Verification, Continuity Check and Remote Defect indication for MPLS Transport
Profile
draft-ietf-mpls-tp-cc-cv-rdi-06
The attached diff file includes the source code modifications for the file
<packet-mpls.c> of wireshark to support the decoding of MPLS-TP(BFD CC, CV)
payloads.
As per the information in the draft mentioned above, the generic associated
channel header is checked for appropriate channel type and a new module has
been defined which calls the BFD CC/CV modules depending in the channel type.
The identification of GAL label(a reserved label with value 13) has also been
done. The source code of wireshark-1.4.6 has been used as the base version.
The changes have also been done in <packet-bfd.c> and a header file
<packet-bfd.h> has been newly added listing the exported BFD routines.
