Hi Shraddha,
For planned link maintenance there still could be traffic disruption.
Even if router with overloaded link is detached from broadcast link, the
latter still could be used by other routers on this one. If router with
overloaded link was DR, traffic between other routers on broadcast link
could be disrupted. Am I correct?

Hi Alexander,
The objective of this draft is to re-route the traffic from the link
that is expected to undergo maintenance
And the case of broadcast links is explained in sec 5.2 which
achieves the objective.
The case you described may be relevant for unplanned link-down events
which is outside the scope of this draft.
Thanks
Shraddha

Hi authors,
In case when the node that has the link to be overloaded is DR (for
broadcast/NBMA link case), taking this link out of service could be
disruptive. What if to modify procedure in such manner that when BDR
receives Link-Overload-sub-TLV from DR, it generates Network LSA in
advance, before taking DR role. The node with overloading link then
waits some time (for example, 3 secs) and changes its interface priority
to 0.
Thank you.
