Import routes from the default routing table into other routing instance tables using policies

by

This article describes the procedure for importing all the routes of a default routing table, inet.0, into the routing instances on SRX and J Series devices.

 

The Problem:

When a term is added in the routing-policy and is specified with a from-condition, it does not give the instance name to import from:

[edit]
# set policy-options policy-statement import-from-default term 1 from instance ? 
Possible completions:
<instance> Routing protocol instance

Step 1. Make a policy-statement as follows:

# set policy-options policy-statement import-from-default term 1 from instance master

# set policy-options policy-statement import-from-default term 1 then accept

Step 2. Import the policy statement into a preconfigured routing-instance instance1:

# set routing-instances instance1 routing-options instance-import import-from-default

After you have completed the above steps, the configuration will look as follows:

# show policy-options
policy-statement import-from-default {
    term 1 {
        from instance master; <-- this is the trick
        then accept;
    }
}

# show routing-instances instance1 
instance-type virtual-router;
interface ge-0/0/0.0;
routing-options {
    instance-import import-from-default;
}

Now when the command show route table instance1.inet.0, is run, you will see the routes imported from the default routing table inet.0.
