Up to version 6.x of frr, I have been able to tie down larger prefixes with a static routing pointing to the discard interface on FreeBSD. eg. the static route entry ip route 10.0.0.0/8 10.128.128.144 # sh ip route 10.0.0.0/8 Routing entry for 10.0.0.0/8 Known via "static", distance 1, metric 0, best Last update 09w0d01h ago * 10.128.128.144, via disc0 where disc0 is # ifconfig disc0 disc0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 65532 inet 10.128.128.144 netmask 0xfffffffc inet6 fe80::1%disc0 prefixlen 64 scopeid 0x8 inet6 2001:db8::1 prefixlen 64 groups: disc nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> however, on frr7.4 this no longer works, On my test box % ifconfig disc0 disc0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 65532 inet 10.128.128.1 netmask 0xfffffffc inet6 fe80::1%disc0 prefixlen 64 scopeid 0x6 groups: disc nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL> i3# conf t i3(config)# ip route 10.0.0.0/8 10.128.128.1 % Warning!!
