Use BFD on a Virtual-Template Interface
I would like to know how I can configure Bidirectional Forward Detection on a Virtual-Template interface. Tested on IOSv and IOS-XE (ISR-4451):
router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
router(config)#interface Virtual-Template99 type tunnel
router(config-if)#bfd ?
% Unrecognized command
router(config-if)#exit
router(config)#interface tunnel 99
router(config-if)#bfd ?
echo Use echo adjunct as bfd detection mechanism
interval Transmit interval between BFD packets
template BFD template
router(config-if)#
This is a FlexVPN environment where we want to use BFD.

Bidirectional Forward Detection (BFD) has been deactivated on virtual and dialer interfaces on newer IOS and IOS-XE versions.
On earlier releases like IOS-XE 3S, the Cisco IOS software incorrectly
allowed configuration of BFD on virtual-template and dialer
interfaces; however, BFD functionality on virtual-template and dialer
interfaces is not supported. Avoid configuring BFD on
virtual-template and dialer interfaces.
That is what the Cisco configuration guide says for BFD on IOS XE:

Thank you for the explanation. So is there another alternative on how to use BFD in a FlexVPN environment? I found a cisco FlexVPN configuration example with BFD, but they use manually created tunnel interfaces on the hubs, i mean what the heck? cisco.com/c/en/us/support/docs/security/flexvpn/…
