First of all BFD on BGP sessions should be vendor agnostic. There should be nothing Juniper or Cisco specific about it. Second, BFD has always been underwhelming on server platforms, like those that Quagga typically runs on. Router vendors typically implement BFD in FPGA or custom silicon right in the forwarding plane. I’m not aware of anyone that can do BFD in the control plane, and support BFD rates less than 100ms. And if you are using a true load balancer, why do you need the fast response time of BFD? A load balancer will be doing health checks, and possibly looking at the response time of the reply traffic versus the request traffic, which would give you a much better view of whether DNS is working or not. BFD in Quagga, would only tell you if Quagga is working, not DNS. > -- > Nick Urbanik http://nicku.org 808-71011 [email protected] > GPG: 7FFA CDC7 5A77 0558 DC7A 790A 16DF EC5B BB9D 2C24 ID: BB9D2C24 > I disclaim, therefore I am. > > _______________________________________________ > Quagga-users mailing list > [email protected] > https://lists.quagga.net/mailman/listinfo/quagga-users Tom _______________________________________________ Quagga-users mailing list [email protected] https://lists.quagga.net/mailman/listinfo/quagga-users
