DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters interface configuration mode for the specified bundle ID.
interface Bundle-Ether bundle-id
Example:
RP/0/RSP0/CPU0:router(config)# interface
Bundle-Ether 1
Step 2
Sets the minimum amount of bandwidth required before a bundle
can be brought up or remain up. The range is from 1 through a
bundle minimum-active bandwidth kbps
Example:
RP/0/RSP0/CPU0:router(config-if)# bundle
minimum-active bandwidth 580000
Step 3
number that varies depending on the platform and the bundle
type.
Sets the number of active links required before a bundle can be
brought up or remain up. The range is from 1 to 32.
bundle minimum-active links links
Example:
RP/0/RSP0/CPU0:router(config-if)# bundle
minimum-active links 2
Step 4
Note
•
When BFD is started on a bundle that is already
active, the BFD state of the bundle is declared
when the BFD state of all the existing active
members is known.

Step 5
Configuring BFD Packet Transmission Intervals and Failure Detection Times on a Bundle
BFD asynchronous packet intervals and failure detection times for BFD sessions on bundle member links are
configured using a combination of the bfd address-family ipv4 minimum-interval and bfd address-family
ipv4 multiplier interface configuration commands on a bundle.
The BFD control packet interval is configured directly using the bfd address-family ipv4 minimum-interval
command. The BFD echo packet interval and all failure detection times are determined by a combination of
the interval and multiplier values in these commands. For more information see the BFD Packet Intervals and
Failure Detection.
To configure the minimum transmission interval and failure detection times for BFD asynchronous mode
control and echo packets on bundle member links, complete these steps:
