I’m indicating the doc fails to justify the required use of IP-level security for a transport encapsulation solution. > Are you suggesting to run a routing protocol should intermix with data > forwarding without security?

For that part of the path anything that protects that payload is sufficient. If the payload needs to be protected elsewhere ie before or after this transit then that is a separate issue. > > If you are suggesting a tutorial is added to a protocol document, provide > operational reasons why this should be contained within a TRILL protocol > specification.
