IP routing conﬁguration using the Java Device Manager 231

Field Description

Rfc1583Compatibility Controls the preference rules used when

choosing among multiple Autonomous

System external link state advertisements

advertising the same destination. When

this is enabled, the preference rule will

be the same as speciﬁed by RFC 1583.

When disabled, the new preference rule, as

described in RFC 2328, will be applicable.

This potentially prevents the routing loops

when Autonomous System external link state

advertisements for the same destination have

been originated from different areas.

LastSpfRun Used to indicate the time the last SPF

calculation was done.
