An IP prefix may be configured as anycast and, as such, the same
value can be advertised by multiple routers. It is useful for other
routers to know that the advertisement is for an anycast prefix.

This document defines a new flag in the OSPFv2 Extended Prefix TLV
Flags to advertise the anycast property. The document also specifies
a companion YANG module for managing this function.

This document is a product of the Link State Routing Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
