Abstract:
It is useful for routers in an OSPFv2 or OSPFv3 routing domain to be
able to associate tags with prefixes. Previously, OSPFv2 and OSPFv3
were relegated to a single tag for AS External and Not-So-Stubby-Area
(NSSA) prefixes. With the flexible encodings provided by OSPFv2
Prefix/Link Attribute Advertisement and OSPFv3 Extended LSAs,
multiple administrative tags may 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.
The ISIS protocol supports a similar mechanism that is described in
RFC 5130.
