Received changes through RFC Editor sync (created document RFC 9825, created became rfc relationship between draft-ietf-lsr-ospf-admin-tags and RFC 9825, set abstract to 'It is useful for routers in OSPFv2 and OSPFv3 routing domains to be able to associate tags with prefixes.  Previously, OSPFv2 and OSPFv3 were relegated to a single tag and only for Autonomous System (AS) External and Not-So-Stubby-Area (NSSA) prefixes.  With the flexible encodings provided by OSPFv2 Prefix/Link Attribute Advertisement and OSPFv3 Extended Link State Advertisements (LSAs), multiple administrative tags may be advertised for all types of prefixes.  These administrative tags can be used for many applications including route redistribution policy, selective prefix prioritization, selective IP Fast Reroute (IPFRR) prefix protection, and many others.', set pages to 18, set standardization level to Proposed Standard, added RFC published event at 2025-07-31)
