+Policy

+
+Routing Policies could be used to tell the router (self or neighbors) what
+routes and their attributes needs to be put into the routing table.
+
+There could be a wide range of routing policies. Some examples are below:
+
+* Set some metric to routes learned from a particular neighbor
+* Set some attributes (like AS PATH or Community value) to advertised routes to neighbors
+* Prefer a specific routing protocol routes over another routing protocol running on the same router
+
+Example

+
+**Policy definition:**
+
+.. code-block:: none
+
+  # Create policy
+  set policy route-map setmet rule 2 action 'permit'
+  set policy route-map setmet rule 2 set as-path-prepend '2 2 2'
+
+  # Apply policy to BGP
+  set protocols bgp 1 neighbor 203.0.113.2 address-family ipv4-unicast route-map import 'setmet'
+  set protocols bgp 1 neighbor 203.0.113.2 address-family ipv4-unicast soft-reconfiguration 'inbound'
+
+Using 'soft-reconfiguration' we get the policy update without bouncing the
+neighbor.
