Therefore we have designed and implemented a system which collects IPv6 (Internet Protocol version 6) network topology information and display it visually. As topology information, we collect LSDB (Link State Database) of OSPFv3 (Open Shortest Path First version 3). The server acts as OSPFv3 router by using ospf6d of Zebra, and collects LSDB. The old system can collect the information of only one OSPF area. Therefore I can collect only gathered information about the topology information of other areas. In this paper, we describe design and implementation of collecting IPv6 network topology information from all OSPF areas. We use ospf6d daemons for each OSPF area. As a result, we can support network whole consisting of all OSPF areas with one server.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術（IOT）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2009-05-21","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"13","bibliographicVolumeNumber":"2009-IOT-5"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"updated":"2025-01-22T02:44:33.040433+00:00","links":{}}
