Hi,
If suddenly license expired, will router unable to be configured with BFD? Originally, router is configured using BFD. Then, noticed that router down and unreachable remotely. But later when I checked the syslog, there was no log that indicate BFD was down after the log that indicate that license was expired.

Hello,
can you enable BFD on an interface rather than globally ?
Router(config-if)#bfd

Hi Georg Pauwen
Same. Cannot configure.
Router(config)#interface bdi1000 Router(config-if)#bfd ? % Unrecognized command Router(config-if)#bfd
Below are the original configuration from backup rancid.
bfd-template single-hop BFD300 interval min-tx 300 min-rx 300 multiplier 3 ! bfd-template single-hop BFD999 interval min-tx 999 min-rx 999 multiplier 3 ! ! interface BDI1000 description ## PrimaryDATA bandwidth 150000 vrf forwarding DATA ip address 10.37.175.38 255.255.255.254 bfd template BFD300 ! interface BDI1001 description ## SecondaryDATA bandwidth 150000 vrf forwarding TMLTE_DATA ip address 10.37.168.214 255.255.255.254 bfd template BFD999 !

Hello,
you need Cisco IOS XE Release 3.5S to run BFD on BDI interfaces. From your previous output it looks like you are running 03.17.01.S.

I don't think the issue is due to the ios version because i have hundred routers using the same ios-xe 3.17s running with BFD and working fine.

Hello,
is this a production router ? I would schedule downtime, reset the entire config (wr erase), reload, and reconfigure everything from scratch...

Thank you for the suggestion. Will try later.
