Routing Policies
ExtremeWare XOS 11.1 Concepts Guide
197
The policy above can be optimized by combining some of the if into a single expression. The compact
form of the policy will look like this:
entry permit_entry {
If match any {
nlri 22.16.0.0/14;
nlri 192.168.0.0/18 exact ;
nlri 10.10.0.0/18;
}
then {
permit;
}
}
entry deny_entry {
if match any {
nlri any/8;
nlri 22.44.66.0/23 exact;
}
then {
deny;
}
}
Translating a route map to a policy
You may be more familiar with using route maps on other Extreme Networks switches. This example
shows the policy equivalent to an ExtremeWare route map.
