Hi Jeff,
I have a similar comment with Dhruv. I am wondering how BGP-LS packages
together TE information. Wouldn't it require IGP-TE to give TE link-state
information to BGP-LS speaker, then BGP-LS packages them into a summary
TE-info? If this is the case, I am not sure how convergence time of BGP-LS can
improve that of IGP-TE? Please correct me if my understanding is not wrong.
Young, all
As much as I am ok with the approach of using PCEP, I am not sure what
you say is always the case. I would guess that the common,
straightforward source of link-state information for BGP-LS is the
IGP-TE, but it does not preclude other sources, including, as per
draft-ietf-idr-ls-distribution direct, static and unknown.
Also, regarding incremental updates, I don't see why they are not
possible with BGP-LS, but I would need to re-read the draft again to be
sure. Can an incremental update consist of a BGP update message with
MP_REACH attribute listing just the descriptors of the link/node and the
link state attribute just encode the TE attributes that have changed? I
may be wrong, but is it stated somewhere that all TLVs need to be listed
at each update?
Thanks
Ramon
