Please can someone help me understand ip rules/routing policies in linux?
For instance consider the below example,
101:from all to 192.168.0.51 lookup table_custom 190:from all to 10.2.3.4 lookup eth1
I understand the rule with priority "101" - from any ip address to 192.168.0.51, lookup the table "table_custom" for the route.
-- But I do not understand the rule "190" - what does lookup an interface mean ?
Thanks in advance.
