bfd for static routes

[ak503]

Are you planning bfd for static routes?

[donaldsharp]

Can you give a description of what you actually would like to do here? As that I do not understand this request

probably this -> https://www.juniper.net/documentation/en_US/junos/topics/example/policy-static-routes-bfd.html

[ak503]

yes, or cisco -> https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/iproute_bfd/configuration/15-e/irbfd-15e-book/irbfd-bfd-static-route-supp.html#concept_A4E4CF767EB54F7BB147585C7FECFEF7

I don't think anyone has plans for this at the moment, at least there is no public manifestation.

I'm adding this to the feature request page and closing the issue ( https://github.com/FRRouting/frr/wiki/Feature-Requests ).

Hi,

What is the latest statest on this?
There are multiple pull requests: #7101 #9704 #10230
But there seems to be no more information on this?
For use with Nokia Airscale which only supports bfd as a "routing protocol" this would be a handy feature to have physical interface failover.

@33Fraise33 , #10230 is the latest one.
when you talk about interface failover, can you please describe more your use case please?

Yes I can.
We are an ISP/MSP in Belgium working together with Nokia for 5G deployments. Their Airscale radio product has no support for dynamic routing but support BFD on static routes.

We create 2 interfaces each with a vlan on it towards the radio. On each transit we have a bfd session on the static route. If the bfd session fails the other route is being used. The same at the Airscale side (they use a trigger for that).
This way we can have failover even if the transit is not directly terminated on the physical switch connected to the radio.

I hope this makes things a little bit more clear.
