Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
This command provides the flexibility to fine-tune the timer values based on individual interface needs when you
configure the ipv6 ospf bfd command in CONFIGURATION mode. Any timer values specified with this
command overrides timers set using the bfd all-neighbors command. Using the no form of this command
does not disable BFD if you configured BFD in CONFIGURATION mode.
To disable BFD on a specific interface while BFD is configured in CONFIGURATION mode, use the keyword
disable.
ipv6 ospf cost
Explicitly specify the cost of sending a packet on an interface.
Syntax
ipv6 ospf interface-cost
Parameters
interface-cost
Enter a unsigned integer value expressed as the link-state metric. The range is from 1 to
65535.
Defaults Default cost based on the bandwidth.

Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information
In general, the path cost is calculated as:
10^8 / bandwidth
Using this formula, the default path cost is calculated as:
• TenGigabitEthernet—Default cost is 1
• FortygigEthernet — Default cost is 1
• Ethernet—Default cost is 10
ipv6 ospf dead-interval
Set the time interval since the last hello-packet was received from a router. After the time interval elapses, the neighboring routers declare
the router down.
Syntax
ipv6 ospf dead-interval seconds
920 Open Shortest Path First (OSPFv2 and OSPFv3)
