The area border router (ABR) generates this LSA to inform other routers in the OSPF domain, that the matching router is an autonomous system boundary router (ASBR), so that the external LSAs (Type 5 / Type 7) it sent may be properly resolved outside its own area. 5 AS-external-LSAs The ASBR Type 5 These describe routes advertised by the ASBR.
The router will usually compare administrative distances to determine which protocol has the lowest value. The router prefers protocols that have a lower assigned administrative distance. For example, OSPF has a default distance of 110, so it is preferred by the router process, over RIP, which has a default distance of 120.
Examples of link-state routing protocols include Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS). [2] The link-state protocol is performed by every switching node in the network (i.e., nodes which are prepared to forward packets; in the Internet, these are called routers). [3]
The link-state ID is the router ID of the described ASBR for type 4 LSAs. In OSPFv3 Inter-Area-Router-LSAs have been renamed. 5 AS-external-LSAs Autonomous System Boundary Router's (ASBR) routing domain these LSAs contain information imported into OSPF from other routing processes. They are flooded to all areas unchanged (except stub and NSSA ...
Quagga is a network routing software suite providing implementations of Open Shortest Path First (OSPF), Routing Information Protocol (RIP), Border Gateway Protocol (BGP) and IS-IS for Unix-like platforms, particularly Linux, Solaris, FreeBSD and NetBSD. [2] [3] Quagga is distributed under the terms of the GNU General Public License v2 (GPL2).
Multiprotocol router - The computer running RRAS can route IP, IPX, and AppleTalk simultaneously. All routable protocols are configured from the same administrative utility. RRAS included two unicast routing protocols, Routing Information Protocol (RIP) and Open Shortest Path First (OSPF) as well as IGMP routing and forwarding features for IP ...
The name is derived from eXtensible Open Router Platform. It supports OSPF, BGP, RIP, PIM, IGMP, OLSR. The product is designed from principles of software modularity and extensibility and aims at exhibiting stability and providing feature requirements for production use while also supporting networking research.

Link-state routing protocols such as Open Shortest Path First (OSPF) and Intermediate System to Intermediate System (IS-IS) elect a designated router on every link to perform flooding of topology information. In wireless ad hoc networks, there is different notion of a link, packets can and do go out the same interface; hence, a different ...
