Dear Authors,
As per draft, for LAN SID Sub-TLV,
7.2. LAN Adj-SID Sub-TLV
The LAN Adj-SID is an optional Sub-TLV of the Router-Link TLV. It
MAY appear multiple times in the Router-Link TLV. It is used to
advertise a SID/Label for an adjacency to a non-DR neighbor on a
broadcast or NBMA network.

"LAN SID is used for non-DR neighbors." We cannot use this Sub TLV to provide
SID for DR router (Neighbor ID is DR's router id in this TLV) ?
It means we need to include "Adj_SID Sub TLV for DR neighbor" and LAN Adj-SID
for other neighbors (including BDR) in the network while advertising Adj- SID
in Router Link TLV for LAN?
Can you please provide clarity for this sub TLV.
Regards,
Veerendranath
