How about “graceful-link-shutdown” ?

However, it is better than “overload”. “pending-maintenance” is a bit long which is why I suggested “pending-shutdown” since “shutdown” is term that vendors have used for eons to described an interface that is not in service.

The use of the term "overload" is unfortunate. But "pending-shutdown" isn’t appealing to me because - at least in most use cases - you aren't actually going to shutdown the link. What you are going to do is make a link the "link of last resort". This seems a better choice. That is not the use case - you are going to take the link down. It is not going to be the "link of last resort”, it is the currently the “link of last resort” and will imminently be taken down. The suggestion from Shraddha that this term was borrowed from IS-IS isn't accurate. "overload" in IS-IS has a very different meaning - it indicates a node either has an incomplete LSDB or (a la RFC 3277<https://urldefense.proofpoint.com/v2/url?u=https-3A__datatracker.ietf.org_doc_rfc3277_&d=DwMGaQ&c=HAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDTXcWzoCI&r=NyjLsr7JA7mvpCJa0YmPdVKcmMXJ31bpbBaNqzCNrng&m=7GM8zN1-Ff2au_agmHAkiNYK2R5Aji-EjpyT8gmgRYU&s=769ndBiWrwubwBNccNtOnDuHr1yMD-W10WuEarCDNgI&e=> )an incomplete forwarding plane. The only use of "link overload" in IS-IS occurs in https://tools.ietf.org/html/draft-ietf-isis-reverse-metric-07#section-3.6<https://urldefense.proofpoint.com/v2/url?u=https-3A__tools.ietf.org_html_draft-2Dietf-2Disis-2Dreverse-2Dmetric-2D07-23section-2D3.6&d=DwMGaQ&c=HAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDTXcWzoCI&r=NyjLsr7JA7mvpCJa0YmPdVKcmMXJ31bpbBaNqzCNrng&m=7GM8zN1-Ff2au_agmHAkiNYK2R5Aji-EjpyT8gmgRYU&s=r_8muG61-ePlkCbqf7qIcHUPHGtjWf_JOH1UXH7lp8U&e=> and this was added recently to support the (very useful) TE use case which was defined in https://tools.ietf.org/html/draft-ietf-ospf-link-overload-11<https://urldefense.proofpoint.com/v2/url?u=https-3A__tools.ietf.org_html_draft-2Dietf-2Dospf-2Dlink-2Doverload-2D11&d=DwMGaQ&c=HAkYuh63rsuhr6Scbfh0UjBXeMK-ndb3voDTXcWzoCI&r=NyjLsr7JA7mvpCJa0YmPdVKcmMXJ31bpbBaNqzCNrng&m=7GM8zN1-Ff2au_agmHAkiNYK2R5Aji-EjpyT8gmgRYU&s=umZHmgXp6i4i0PAyZbsDS0iorBurDZsFIyvaVVXEHb0&e=> . When this was done the term "link-overload" was cut and pasted from the OSPF draft. I think this should also be changed in the IS-IS draft. Agreed.
