Първо трябва да добавим таблица например с номер 200 и име T1 в /etc/iproute2/rt_tables
255 local
254 main
253 default
0 unspec
#
# local
#
#1 inr.ruhep
201 T1
След което следва самата конфигурация
ip route add 127.0.0.0/8 dev lo table T1
ip route add 192.168.1.0/30 dev eth0 src 192.168.1.2 table T1
ip route add 172.16.10.0/24 dev eth1 src 172.16.10.1 table T1
ip route add default via 192.168.1.1 table T1
