Issue:

DNS Anycast with BFD disabled cause DNS service to be non-responsive during restart. which leads to the black-hole of DNS traffic. and if there are any ZRQ happening at the same time it increases the downtime.

 

Solution:

 

one fix is to enable BFD, but that will cause BGP to flap during every DNS service restart.

 

Is there a better way to fix it?
