In addition in the case of a planned restart prior to restarting, the restarting node SHOULD originate the TE LSAs containing Link TLV with 0 as unreserved bandwidth, and if the Link has LSC or FSC as its Switching Capability then also with 0 as Max LSP Bandwidth. This would discourage new LSP establishment through the restarting router. Neighbors of the restarting node should continue advertise the actual unreserved bandwidth on the TE links from the neighbors to that node.
