The following errata report has been submitted for RFC3101, "The OSPF Not-So-Stubby Area (NSSA) Option".
-------------------------------------- You may review the report below and at: http://www.rfc-editor.org/errata_search.php?rfc=3101&eid=4767 -------------------------------------- Type: Technical Reported by: Chao Fu <[email protected]> Section: 2.5.(6).(e) Original Text ------------- (e) If the current LSA is functionally the same as an installed LSA (i.e., same destination, cost and non-zero forwarding address) then apply the following priorities in deciding which LSA is preferred: 1. A Type-7 LSA with the P-bit set. 2. A Type-5 LSA. 3. The LSA with the higher router ID. [NSSA] Corrected Text -------------- NULL (it should be deleted because no LSAs would be compared here.) Notes ----- If one LSA is Type-5 and the other is Type-7, one of them would be rejected at step (2.5.(3) ( please refer to OSPF mail list: https://mailarchive.ietf.org/arch/msg/ospf/KBoh5T75o-s7n_bL1knrc6uVlTs ). If both of them are Type-7 LSAs, one of them would be flushed according 2.4: If two NSSA routers, both reachable from one another over the NSSA, originate functionally equivalent Type-7 LSAs (i.e., same destination, cost and non-zero forwarding address), then the router having the least preferred LSA should flush its LSA. As a result, rule (e) would never be applied and should be removed. Instructions: ------------- This erratum is currently posted as "Reported". If necessary, please use "Reply All" to discuss whether it should be verified or rejected. When a decision is reached, the verifying party (IESG) can log in to change the status and edit the report, if necessary. -------------------------------------- RFC3101 (draft-ietf-ospf-nssa-update-11) -------------------------------------- Title : The OSPF Not-So-Stubby Area (NSSA) Option Publication Date : January 2003 Author(s) : P.
