Ospf Commands - ZyXEL Communications XS3800-28 Cli Reference Manual

This chapter explains how to use commands to configure the Open Shortest Path First (OSPF) routing
protocol on the Switch.
61.1 OSPF Overview
OSPF (Open Shortest Path First) is a link-state protocol designed to distribute routing information within an
autonomous system (AS). An autonomous system is a collection of networks using a common routing
protocol to exchange routing information.
The Switch uses OSPFv2 for IPv4, and also supports OSPFv3 to work with IPv6. OSPFv2 and OSPFv3 are
quite similar. The OSPF mechanisms and algorithms are not changed but there are two new Link State
Advertisements (LSA) types in OSPFv3. OSPFv2 uses plain text or MD5 authentication, while no
authentication is required for OSPFv3 on the Switch. Their packet format is different, too.
Note: You must purchase the Advance Routing service license and go to myZyxel to activate
it for your Switch in order to use advanced L3 routing features, such as RIPng and
OSPFv3 for IPv6. See
61.2 Command Summary
