事前学習 LSA type
- Areaの定義
OSPFv3 LSA typeについてまとめる前に、Areaの意味について確認します。Cisco Pressの書物やCCOでは、以下の意味でAreaという言葉を用いているようです。IntraとInterが紛らわしいので、しっかり確認しておきましょう。
| 用語 | 意味 |
| Intra-Area | OSPFドメイン内のArea番号が一致する範囲 |
| Inter-Area | OPSFドメイン内のArea番号が一致しない範囲 |
| External-Area | OSPFドメイン外 |
- LSA type
ipv4と比較して、LSA type1, 2に一部変更があります。type1,2の一部がtype8,9に移行しました。それ以外は、ipv4と同じ構成になっています。
| LSA type | name | OSPFとの対応 | Routing table | show ipv6 ospf database |
| 0x2001 | Router LSA | LSA type1に相当（但し、一部Link LSAに移行） | O | Router Link States |
| 0x2002 | Network LSA | LSA type2に相当（但し、一部Intra-Area Prefix LSAに移行） | O | Net Link States |
| 0x2008 | Link LSA | LSA type1の一部 | O | Link (Type-8) Link States |
| 0x2009 | Intra-Area Prefix LSA | LSA type2の一部 | O | Intra Area Prefix Link States |
| 0x2003 | Inter-Area Prefix LSA | LSA Type 3 | OI | Inter Area Prefix Link States |
| 0x2004 | Inter-Area Router LSA | LSA Type 4 | OI | Inter Area Router Link States |
| 0x2005 | AS-Eternal LSA | LSA Type 5 | OE1, OE2 | Type-5 AS External Link States |
| 0x2007 | Type-7 LSA | LSA Type 7 | ON1, ON2 | Type-7 AS External Link States |
検証1 初期設定の確認
初期設定時のルーティングテーブルと LSA databaseを確認します。LSA databaseは読むのに時間がかかると思いますが、よく読むと、Intra-Area以外はipv4と全く同じ表記である事が分かります。また、Intra-Areaに着目しても、一部がtype8,9に移行したと思えば、理解する事ができると思います。

- tottaly stubの設定
tottaly stubの設定を以下の要領で行います。しかし、R3に設定を投入する事ができませんでした。
「ASBRにstubの設定はできません」とエラーが出力されます。IPv4の時は、ASBRであろうがお構いなしにSTUBの設定ができました（「トップページ/動作検証 ネットワーク系/20100421 OSPF stub area」を参照）が、IPv6ではちゃんとエラーメッセージを出力してくれるようです。ちょっと、お利口になったようです。

tottaly stubの設定を削除します。

- totally nssaの設定
以下の要領でtotally nssaの設定を行います。
R2(config)#ipv6 router ospf 1 R2(config-rtr)#area 1 nssa no-summary R3(config)#ipv6 router ospf 1 R3(config-rtr)#area 1 nssa
- ルーティングテーブルとLSAの確認
ルーティングテーブルとLSA databaseを確認します。IPv4と同様に、R3にデフォルトルートが通知されている事やR3からR2へType 7のLSAが送信されている事が確認できると思います。
