+== Otherwise EIP
+
+The Otherwise EIP is related to
http://www.enterpriseintegrationpatterns.com/ContentBasedRouter.html[Content
+Based Router] from the link:enterprise-integration-patterns.html[EIP
+patterns]
+
+image:http://www.enterpriseintegrationpatterns.com/img/ContentBasedRouter.gif[image]
+
+=== Options
+
+// eip options: START
+The Otherwise EIP has no options.
+// eip options: END
+
+=== Examples
+
+The following example shows how to route a request from an input
+*seda:a* endpoint to either *seda:b*, *seda:c* or *seda:d* depending on
+the evaluation of various link:predicate.html[Predicate] expressions
+
+[source,java]
+----
+RouteBuilder builder = new RouteBuilder() {
+ public void configure() {
+ from("direct:a")
+ .choice()
+ .when(simple("${header.foo} == 'bar'"))
+ .to("direct:b")
+ .when(simple("${header.foo} == 'cheese'"))
+ .to("direct:c")
+ .otherwise()
+ .to("direct:d");
+ }
+};
+----
+
+
+And the same example using XML:
+
+[source,xml]
+----
+<camelContext xmlns="http://camel.apache.org/schema/spring";>
+ <route>
+ <from uri="direct:a"/>
+ <choice>
+ <when>
+ <simple>${header.foo} == 'bar'</simple>
+ <to uri="direct:b"/>
+ </when>
+ <when>
+ <simple>${header.foo} == 'cheese'</simple>
+ <to uri="direct:c"/>
+ </when>
+ <otherwise>
+ <to uri="direct:d"/>
+ </otherwise>
+ </choice>
+ </route>
+</camelContext>
