These changes are based on the sysctl recommendations by Frr [1]. Not all recommendations have been incorporated, e.g., ip forwarding is not enabled per interface, because in Infix this is an opt-in feature. A readme.txt has been added, documenting the various settings. New for IPv4: - Adjust IGMP max memberships: 20 -> 1000 - Use neighbor information on nexthop selection - Use inbound interface address on ICMP errors - Ignore routes with link down - Disable rp_filter ARP settings have been changed to better fit routers, i.e., systems with multiple interfaces: - Always use best local address when sending ARP - Only reply to ARP if target IP is on the inbound interface - Generate ARP requests when device is brought up or HW address changes New for IPv6: - Keep static global addresses on link down - Ignore routes with link down Fixes #829 [1]: https://github.com/FRRouting/frr/blob/master/doc/user/Useful_Sysctl_Settings.md Signed-off-by: Joachim Wiberg <troglobit@gmail.com>
