OSPF TE State
Select one of the following options:
Enable - (default) This interface is allowed to run IP OSPF traffic
engineering extension per RFC 3630.
Disable - This interface is prevented from running IP OSPF
traffic engineering extension per RFC 3630.
Interface Type
Select one of the following options:
Broadcast – (default for Ethernet and IP VPN cloud interfaces) A
broadcast network supports many routers and has a Designated
Router that addresses a single physical message to all attached
routers. The Hello protocol dynamically discovers neighboring
routers on these networks.
NBMA – (default for Frame Relay and ATM interfaces) A
Non-Broadcast Multiple Access (NBMA) network supports
many routers, but does not have broadcast capability. This type of
network requires full-mesh connectivity.
Point-to-Multipoint – A point-to-multipoint (PMP) network
supports multiple router connections, which are treated like
point-to-point connections. The IP addresses of the remote
router’s interfaces are advertised.
Point-to-Point – (default for PPP interfaces) A point-to-point
network joins two routers together. The IP address of the
neighboring router’s interface is advertised. Hello packets are
sent to the neighbor at regular intervals based on the value that
you specify for the Hello Interval parameter. Note that this
selection may not be available, depending on the type of data link
interface. For example, this selection is not available for ATM
and Frame Relay interfaces.
Multicast
Forwarding
Specify one of the following:
Multicast — (default) The OSPF interface forwards multicast
traffic to a multicast data link address. Do not change the default
unless you want to block multicast traffic or (in rare
circumstances) forward multicast traffic to a unicast data link
address.
Unicast — The OSPF interface forwards multicast traffic to a
unicast data link address (Ethernet MAC address, Frame Relay
DLCI, ATM VPI/VCI, etc.).
Blocked — The OSPF interface does not forward multicast traffic
(but MOSPF continues to run).
Demand
Not available for this release.
