Title : The Generalized TTL Security Hack (GTSH)

The BGP TTL Security Hack (BTSH) was designed to protect the BGP
[RFC1771] infrastructure from CPU-utilization based attacks. This
document generalizes the BTSH technique for use by other protocols
such as MSDP [MSDP] and Bidirectional Forwarding Detection [BFD].
While the Generalized TTL Security Hack (GTSH) is most effective in
protecting directly connected protocol peers, it can also provide a
lower level of protection to multi-hop sessions. Use of multi-hop
GTSH should be considered on a case-by-case basis.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
