Hi!

The IRS topology effort is not about what is visible to what devices per se; its about revealing different topological components in a normalized topology 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.

Hi Authors,
“…and visible within the Link State Database (LSDB) of an active IGP, but also network elements who are active, but invisible to a LSDB (e.g.: L2 Ethernet switches, ROADM's, etc.)”
Shouldn’t ROADMs topology be visible to IGP? Perhaps you intend to say optical line amplifier (OLA).
Regards,
Iftekhar
