Field Description
Network Mask
The IP address mask for the advertised destination.
E – bit
The type of external metric. If the E – bit is set, the metric specified
is a Type 2 external metric. This means the metric is considered
larger than any link state path. If the E – bit is zero, the specified
metric is a Type 1 external metric. This means that is comparable
directly to the link state metric.
Forwarding Address
Data traffic for the advertised destination will be forwarded to this
address. If the Forwarding Address is set to 0.0.0.0, data traffic will
be forwarded instead to the advertisement’s originator.
TOS
The Type of Service that the following cost is relevant to.
Metric
The cost of this route. The interpretation of this metric depends on
the external type indication (the E – bit above).
External Route Tag
A 32-bit field attached to each external route. This is not used by
the OSPF protocol itself.
