Zebra OSPFv 3 status Yasuhiro Ohara yasu@sfc. wide. ad. jp WIDE Project

Implementation • RFC 2740 - OSPF for IPv 6 • A free, open source code from scratch – about 17, 000 lines in C • A common platform : “Zebra” – – Uses Zebra’s Library (tasking, timers, etc. ) Portability (tested on *BSD) Configurable via Telnet Routing info can be exchanged with other protocols (RIPng, BGP 4+)

Functionality • Stability improved after IETF 48 • Supported – OSPF Backbone (0. 0) routing – Route exchange with other protocols • Not yet supported – Area function – SNMP • Full support before 2001/04

The testbed network • • 33 Routers currently running this system Maximum 13 hops Many Point-To-Point Links with ATM 9 Transit Broadcast Segments 170 LSAs (AS: 95, Area: 75) 143 routes (ASE: 93, Intra: 50) Default advertised from AS Border

Statistics • Data gathering (duration): 72 hour • CPU load – SPF frequency: • maximum interval: 15 hours (at least) • average interval: 13 minutes – Time taken to run SPF • maximum: 66 mili-seconds • average: 25 mili-seconds

Statistics(Link bandwidth) • OSPFv 3 (statistics) – Point-To-Point: • 209 bps (Tx: 104 bps Rx: 105 bps) – Broadcast (DR, 3 neighbors): • 430 bps (Tx: 212 bps Rx: 218 bps) • RIPng (calculated) – 143 routes * 20 bytes * 8 (bits/byte) / 30 seconds • 762 bps

TODOs to Full support • Synchronization with BGP • Area – Transit, Stub, NSSA, Virtual link • SNMP(MIB) • What else?
