Adding OSPF Area Interfaces
License:

Supported Devices:
Series 3
You can configure a subset of the interfaces assigned to the virtual router for OSPF. The following list
describes the options you can specify on each interface.

Interfaces

Interfaces tab are not available.
Interfaces tab are not available.
Type
Select the type of OSPF interface from the following choices:
–
Broadcast — On broadcast networks, flooding and hello messages are sent using multicasts, a
single packet for all the neighbors. The option designates a router to be responsible for
synchronizing the link state databases and originating network link state advertisements. This
network type cannot be used on physically non-broadcast multiple-access (NBMP) networks
and on unnumbered networks without proper IP prefixes.

synchronizing the link state databases and originating network link state advertisements. This
network type cannot be used on physically non-broadcast multiple-access (NBMP) networks
and on unnumbered networks without proper IP prefixes.
–
Point-to-Point (PtP) — Point-to-point networks connect just two routers together. No election
is performed and no network link state advertisement is originated, which makes it simpler and
faster to establish. This network type is useful not only for physically PtP interfaces, but also
for broadcast networks used as PtP links. This network type cannot be used on physically
NBMP networks.

for broadcast networks used as PtP links. This network type cannot be used on physically
NBMP networks.
–
Non-Broadcast — On NBMP networks, the packets are sent to each neighbor separately because
of the lack of multicast capabilities. Similar to broadcast networks, the option designates a
router, which plays a central role in the propagation of link state advertisements. This network
type cannot be used on unnumbered networks.

–
Autodetect — The system determines the correct type based on the specified interface.
Cost
Specify the output cost of the interface.
Stub
Specify whether the interface should listen for OSPF traffic and transmit its own traffic.
