6.20.10.4 Configuring OSPF Interfaces
A routing interface should be specified for any local subnet that needs to
communicate with other network segments located on this router or elsewhere
in the network. First configure a VLAN for each subnet that will be directly
connected to this router, assign IP interfaces to each VLAN (that is, one primary
interface and one or more secondary interfaces), and then use the OSPF /
Network Area Address Configuration page to assign an interface address range
to an OSPF area.
After assigning a routing interface to an OSPF area, use the OSPF / Interface
Configuration page to configure the interface-specific parameters used by OSPF
to select the designated router, control the timing of link state advertisements,
set the cost used to select preferred paths, and specify the method used to
authenticate routing messages.
Field Attributes
OSPF Interface List
• VLAN ID – The VLAN to which an IP interface has been assigned.
• Interface IP – The IP interface associated with the selected VLAN.
• Area ID – The area to which this interface has been assigned.
• Designated Router – Designated router for this area.
• Backup Designated Router – Designated backup router for this area.
• Entry Count – The number of IP interfaces assigned to this VLAN.
Note: This router supports up 64 OSPF interfaces.
Detail Interface Configuration
• VLAN ID – The VLAN corresponding to the selected interface.
• Rtr Priority – Sets the interface priority for this router. (Range: 0-255;
Default: 1)
• A designated router (DR) and backup designated router (BDR) is
elected for each OSPF area based on Router Priority. The DR forms
an active adjacency to all other routers in the area to exchange
