Architecture: OpenBSD.amd64 Machine : amd64 >Description: When option classless-static-routes is set at the dhcp server no routes are added at all, neither the additional routes nor the default route. >How-To-Repeat: define a subnet in dhcpd.conf like that: subnet 192.168.1.0 netmask 255.255.255.0 { option routers 192.168.1.1; option classless-static-routes 0/0 192.168.1.1, 192.168.2.0/24 192.168.1.2; ... } >Fix: Without option 121 the default route is set. dmesg: OpenBSD 6.9 (GENERIC.MP) #12: Tue Apr 6 15:41:46 GMT 2021 uwe@FT-GV164M2:/usr/src/sys/arch/amd64/compile/GENERIC.MP real mem = 17018589184 (16230MB) avail mem = 16487419904 (15723MB) random: good seed from bootblocks mpath0 at root scsibus0 at mpath0: 256 targets mainbus0 at root bios0 at mainbus0: SMBIOS rev. 3.0 @ 0xeab60 (103 entries) bios0: vendor Dell Inc. version "1.16.1" date 10/03/2019 bios0: Dell Inc.
