Introduction; Area Authentication - Allied Telesis SwitchBlade x908 Series Software Reference Manual

Introduction

This chapter provides an alphabetical reference for each of the OSPF Commands.

area authentication

Use this command to enable authentication for an OSPF area. By default, no authentication
occurs.
Specifying the area authentication sets the authentication to Type 1 authentication or the
Simple Text password authentication (details in RFC 2328). All OSPF packets transmitted in
this area must have the same password in their OSPF header. This ensures that only routers
that have the correct password may join the routing domain.
Give all routers that are to communicate with each other through OSPF the same
authentication password.
Use the ip ospf authentication-key command to specify a Simple Text password. Use the
ip ospf message-digest-key command to specify MD5 password.
The no form removes the authentication specification for an area.

entered in either dotted decimal format or normal decimal format.

For example the values dotted decimal 0.0.1.2 and decimal 258 would
both define the same area OSPF Area ID.
