Expand description
Inter-Area-Prefix-LSAs (v3)
Inter-area-prefix-LSAs have LS type equal to 0x2003. These LSAs are the IPv6 equivalent of OSPF for IPv4’s type 3 summary-LSAs (see Section 12.4.3 of [OSPFV2]). Originated by area border routers, they describe routes to IPv6 address prefixes that belong to other areas. A separate inter-area-prefix-LSA is originated for each IPv6 address prefix. For details concerning the construction of inter-area- prefix-LSAs, see Section 4.4.3.4.
For stub areas, inter-area-prefix-LSAs can also be used to describe a (per-area) default route. Default summary routes are used in stub areas instead of flooding a complete set of external routes. When describing a default summary route, the inter-area-prefix-LSA’s PrefixLength is set to 0.
