Perform one of the following steps:
• ip address ipv4-address mask
• ipv6 address ipv6-address/mask
Example:
Configuring an IPv4 address for the interface:
Device(config-if)# ip address
10.201.201.1 255.255.255.0
Configuring an IPv6 address for the interface:
Device(config-if)# ipv6 address
2001:db8:1:1::1/32
bfd interval milliseconds min_rx milliseconds
multiplier interval-multiplier
Example:
Device(config-if)# bfd interval 100
min_rx 100 multiplier 3

Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters global configuration mode.
Configures an IP address for the interface.
Enables BFD on the interface.
The BFD interval configuration is removed when
the subinterface on which it is configured is
removed.
The BFD interval configuration is not removed
when:
• an IPv4 address is removed from an interface
• an IPv6 address is removed from an interface
• IPv6 is disabled from an interface
