Service Manual

Usage
Information
This command provides the flexibility to fine-tune the timer values based on individual interface needs
when you configure ipv6 ospf BFD 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 configure BFD in CONFIGURATION mode.
To disable BFD on a specific interface while you configure BFD in CONFIGURATION mode, use the
keyword disable.

In general, the path cost is calculated as:
10^8 / bandwidth
Using this formula, the default path cost is calculated as:
● GigabitEthernet—Default cost is 1
● TenGigabitEthernet—Default cost is 1
● FortygigEthernet — Default cost is 1
● Ethernet—Default cost is 10
ipv6 ospf dead-interval
