4.5.3. OSPF Components
Metric
Bandwidth
Authentication
All OSPF protocol exchanges can be authenticated using a simple password or MD5 cryptographic
hashes.
If Use Default for Router Process is enabled then the values configured in the router process
properties are used. If this is not enabled then the following options are available:
• No authentication.
• Passphrase.
• MD5 Digest.
Advanced
Hello Interval
Router Dead Interval
RXMT Interval
InfTrans Delay
Wait Interval
Router Priority
an OSPF Neighbour object.
Using VPN tunnels is discussed further in Section 4.5.5, "Setting Up
OSPF".
• Point-to-Multipoint - The Point-to-Multipoint interface type is a
collection of Point-to-Point networks, where there is more then one
router in a link that does not have OSI Layer 2 broadcast/multicast
capabilities.
Specifies the metric for this OSPF interface. This represents the "cost" of
sending packets over this interface. This cost is inversely proportional to the
bandwidth of the interface.
If the metric is not specified, the bandwidth is specified instead. If the
bandwidth is known then this can be specified directly instead of the metric.
Specifies the number of seconds between Hello packets sent on the
interface.
If not Hello packets are received from a neighbor within this
interval then that neighbor router will be considered to be out of
operation.
Specifies the number of seconds between retransmissions of LSAs
to neighbors on this interface.
Specifies the estimated transmit delay for the interface. This value
represents the maximum time it takes to forward a LSA packet
trough the router.
Specifies the number of seconds between the interface brought up
and the election of the DR and BDR. This value should be higher
than the hello interval.
Specifies the router priority, a higher number increases this routers
chance of becoming a DR or a BDR. If 0 is specified then this
router will not be eligible in the DR/BDR election.
Note
An HA cluster will always have 0 as router priority,
and can never be used as a DR or BDR.
