How to get ospf routing information with C code？

[LoveCPro]

-->

• OS Version:openwrt 19.07

• FRR Version: frr-7.3.1

Now I need to get all the ospf routing details in frr through C code outside frr, has anyone done it??

Whether ospf routing data supports external communication？

Do you mean using FRR as a library for your own program?

There is an ospf api module that exports some ospf info - see the doc here:
