Re: Use of advisory attribute

Shane,

Many moons ago ANS used the advisory attribute for transit
across their network and they required all their route objects
to have such a field.  Other than that use I never heard
of anyone using it for anything other purpose.  To my knowledge,
ANS was the reason for the advisory attribute.

When we converted to RPSL we dropped support for the advisory
attribute and it was filtered out of all route objects.

This suprises me since to my knowledge we no longer supported
this attribute.  So I grep'd our production DB cache for 'advisory'
and it did not show up.

So where are you finding all these occurences?
