Chapter 54 Configuring Routing Policies on Firewall Devices
Configuring OSPFv3
Disable MTU mismatch
detection
Check this box to disable the OSPFv3 MTU mismatch detection when
database description (DBD) packets are received.
Flood Reduction Check this box to suppress unnecessary flooding of LSAs in stable
topologies.
Point-to-point Network Check this box to define this as a link to a point-to-point network; that
is, a network between two routing devices. All neighbors on a
point-to-point network establish adjacency and there is no designated
router.
This option is unavailable when the Broadcast option is selected.
Broadcast Check this box to define this as a link to a network with multiple
routing devices. Such networks establish a designated router (DR), as
well as a backup designated router (BDR), that controls LSA flooding
on the network.
This option is unavailable when the Point-to-point Network option is
selected.
Cost The cost of sending a packet through the interface. Link cost is an
arbitrary number used in shortest path first calculations. If you do not
assign a value, the configured reference bandwidth divided by the
interface port speed is used. (The default reference bandwidth is 40
Gb/sec.)
Priority Assign an OSPFv3 priority to this interface. Valid values for this setting
range from 0 to 255. Entering 0 for this setting makes the device
ineligible to become the designated router or backup designated router.
This setting does not apply to interfaces that are configured as
point-to-point, non-broadcast interfaces.
When two routing devices connect to a network, both attempt to
become the designated router. The device with the higher priority
becomes the designated router. If there is a tie, the router with the
higher router ID becomes the designated router.
Dead Interval If no hello packets are received from a neighbor within this interval,
that device is designated as inactive. Valid values range from 1 to
65535. The default value for this setting is four times the hello interval.
Poll Interval If a neighboring device is inactive, it may be necessary to continue
sending hello packets to that neighbor. The hello packets are sent at this
reduced interval, which should be larger than the hello interval.
Retransmit Interval The time, in seconds, between LSA retransmissions for adjacent
neighbors. When a router sends an LSA to a neighbor, it keeps the LSA
until it receives an acknowledgment. If an acknowledgment is not
received within this interval, it will resend the LSA. Be conservative
when setting this value, or needless retransmission can result. The
value should be larger for serial lines and virtual links. Valid values
range from 1 to 65535 seconds.
