Hi Manav,

This is a good point. Any router which fully supports RFC5838 should be using LLS (see section 2.7), so will be devices in the field using LLS before any support AT.

Dear Manav,

I agree with all the points mentioned by you in the below mail.
Only problem if we put AT before LLS is, there might exist a router in the
network who supports LLS but not AT (less probability). He will not be able
to decode LLS correctly when packet arrives with AT and LLS. Compatibility
need to support for AT as well as LLS this seems to be a issue.


Thanks
Rajesh
