Abstract Abstract
This document reports the results of the OSPFv2 Prefix/Link This document reports the results of the OSPFv2 Prefix/Link
Attributes implementation survey. The survey has seven questions Attributes implementation survey. The survey has seven questions
related to the implementer's support of OSPFv2 Prefix/Link related to the implementer's support of OSPFv2 Prefix/Link
Attributes. After a brief summary of the results, each response is Attributes. After a brief summary of the results, each response is
listed. This document contains responses from six implementers who listed. This document contains responses from six implementers who
completed the survey. No external means were used to verify the completed the survey. No external means were used to verify the
