Basic IPX Route Filter Rules and Syntax
At a minimum, every
Every line in an IPX Route filter set must begin with the actions permit or deny, or the comment indicator #.
•Lines which begin with permit specify that information meeting the conditions should be included in the IPX routing table.
•Lines which begin with deny specify that information meeting the condi- tions should not be included in the IPX routing table.
•Lines which begin with # specify that the text on the line is a comment and should be ignored.
The network expression uses a set of operators to specify the conditions under which the rule will be satisfied. These operators are discussed below:
•eq, ==, or = These are acceptable ways of writing an "equality" operator which will match if the value in the routing information is equal to the value specified in the network expression.
•lt or < These are acceptable ways of writing a "less than" operator which will match if the value in the routing information is less than the value specified in the network expression.
•lteq, le, <=, or =< These are acceptable ways of writing a "less than or equal to" operator which will match if the value in the routing informa- tion is less than or equal to the value specified in the network expression.
•gt or > These are acceptable ways of writing a "greater than" operator which will match if the value in the routing information is greater than the value specified in the network expression.
•gteq, ge, >=, or => These are acceptable ways of writing a "greater than or equal to" operator which will match if the value in the routing infor- mation is greater than or equal to the value specified in the network expression.
•ne, <>, or != These are acceptable ways of writing an "inequality" oper- ator which will match if the value in the routing information is not equal to the value specified in the network expression.
The keyword all may be used to specify all network number values in the network expression.
