The branch stable/13 has been updated by allanjude: URL: https://cgit.FreeBSD.org/src/commit/?id=c6ec1b441ad3fdfa2d3a22d0b66d53006c5e292b commit c6ec1b441ad3fdfa2d3a22d0b66d53006c5e292b Author: Andrew Fengler <andrew.fengler@scaleengine.com> AuthorDate: 2021-05-12 01:59:10 +0000 Commit: Allan Jude <allanjude@FreeBSD.org> CommitDate: 2022-12-02 21:27:57 +0000 Add support for adding default routes for other FIBs Make rc.d/routing read defaultrouter_fibN and ipv6_defaultrouter_fibN, and set it as the default gateway for FIB N, where N is from 1 to (net.fibs - 1) This allows adding gateways for multiple FIBs in the same format as the main gateway.
