internal OSPF cost. When selecting a path, the internal OSPF cost is added to the AB boundary
router to the external metrics.
Select 2 for routing protocols whose external metrics are not comparable to the OSPF cost. In this
case, the external cost of the AB boundary router is used in path decision to a destination.
Metric Value Enter a route cost (between 0 and 16777214).

26.4 Configuring OSPF Areas
To ensure that the ES receives only routing information from a trusted layer 3 devices, activate authentication. The
OSPF supports three authentication methods:
• None – no authentication is used.
• Simple – authenticate link state updates using an 8 printable ASCII character password.
• MD5 – authenticate link state updates using a 16 printable ASCII character password.
To configure an area, set the related fields in the OSPF Configuration screen.
