Hi!

The IR= S topology effort is not about what is visible to what devices per se;= its about revealing different topological components in a normalized topol= ogy database. So in this example, capturing the active information (which is visible via LSDB/IGP routing protocols), = is complimented with other inactive (or passive) topological components.&nb= sp;

Hi Authors,

=93=85and visible wit= hin the Link State Database (LSDB) of an active IGP, but also network eleme= nts who are active, but invisible to a LSDB (e.g.: L2 Ethernet switches, RO= ADM's, etc.)=94

Shouldn=92t ROADMs to= pology be visible to IGP? Perhaps you intend to say optical line amplifier = (OLA).

Regards,

Iftekhar
