Abstract:
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 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 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.
The ISIS protocol supports a similar mechanism that is described in
RFC 5130.
