<p>Hi Liviu.</p>
<p><br>
</p>
<p>Thank you.</p>
<p><br>
</p>
<p>That is the point I want to discuss!</p>
<p><br>
</p>
<p>According to the example from the documentation, the lookup() is in <br>
</p>
<p><br>
</p>
<p><span style="color: rgb(0, 111, 201); font-size: 10pt;">route[relay] {</span></p>
<p><span style="color: rgb(0, 111, 201); font-size: 10pt;">}</span></p>
<p><br>
</p>
<p>However, in my code the lookup() is in <br>
</p>
<p><br>
</p>
<p><span style="color: rgb(0, 111, 201); font-size: 10pt;">route{</span></p>
<p><br>
</p>
<p><span style="color: rgb(0, 111, 201); font-size: 10pt;">}</span></p>
<p><br>
</p>
<p>Even with lookup() in rout{...}, does it will populate the attributes of each branch in my "attr_avp" and I will be able to access them within branch_route?</p>
<p><br>
</p>
<p>Best regards!</p>
<p><br>

<p><tt>Yes, lookup() will populate the attributes of each branch in your "attr_avp", and you can access them through $T_branch_idx within branch_route. [1]</tt></p>
