Zinin, A. Lindem, D. Yeung 8 Status: Informational 9 Date: April 2003 10 Mailbox: zinin@psg.com, acee@redback.com, 11 myeung@procket.com 12 Pages: 12 13 Characters: 24326 14 Updates/Obsoletes/SeeAlso: None 16 I-D Tag: draft-ietf-ospf-abr-alt-05.txt 18 URL: ftp://ftp.rfc-editor.org/in-notes/rfc3509.txt 20 Open Shortest Path First (OSPF) is a link-state intra-domain routing 21 protocol used for routing in IP networks. Though the definition of 22 the Area Border Router (ABR) in the OSPF specification does not 23 require a router with multiple attached areas to have a backbone 24 connection, it is actually necessary to provide successful routing to 25 the inter-area and external destinations. If this requirement is not 26 met, all traffic destined for the areas not connected to such an ABR 27 or out of the OSPF domain, is dropped. This document describes 28 alternative ABR behaviors implemented in Cisco and IBM routers. 30 This document is a product of the Open Shortest Path First IGP Working 31 Group of the IETF. 33 This memo provides information for the Internet community.
