Subject: WG Last Call: draft-ietf-lsr-ospf-ls-link-infinity-11 (Ends 2025-12-09)
This message starts a 3-week WG Last Call for this document. Abstract: In certain scenarios, it is necessary to advertise OSPF links that are not applicable to the default SPF (Shortest Path First) calculation for other purposes. In order to advertise these links and not use them in the base SPF calculation, the metric LSLinkInfinity (0xffff) is used to specify that the link is unreachable. Stub Router Advertisement (RFC 6987) defines MaxLinkMetric (0xffff) to indicate a router-LSA link should not be used for transit traffic. When an OSPFv2 router supports the Unreachable Link support capability defined in this document, OSPFv2 Stub Router links are advertised as MaxReachableLinkMetric (0xfffe) rather than MaxLinkMetric (0xffff). This document updates RFC 6987 and RFC 8770 with respect to the advertisement of MaxReachableLinkMetric rather than MaxLinkMetric.
