Configuring a Final Action in Routing Policies
Logging Matches to a Routing Policy Term
In addition to specifying an action using the then statement in a named term, you can
also specify an action using the then statement in an unnamed term, as follows:
[edit]
policy-options {
policy-statement policy-name {
term term-name {
from {
family family-name;
match-conditions;
policy subroutine-policy-name;
prefix-list name;
route-filter destination-prefix match-type ;
source-address-filter source-prefix match-type ;
}
to {
match-conditions;
policy subroutine-policy-name;
}
then {
actions;
}
}
then action;
}
}
If you specify the trace action, the match is logged to a trace file. To set up a trace file,
you must specify the following elements in the global traceoptions statement:
• Trace filename
• policy option in the flag statement
For more information about the global traceoptions statement, see the Junos OS Routing
Protocols Configuration Guide.
The following example uses the trace filename of policy-log:
[edit]
routing-options {
traceoptions {
file “policy-log";
flag policy;
}
}
This action does not affect the flow control during routing policy evaluation.
