[BGPCEP-679] "Peer for IpAddress.. already present" error occurs when features-bgp starts

Sun, 3 Mar 2019 11:50:04 +0000

We introduce features-bgp in our feature pom as following:

<dependency>
<groupId>org.opendaylight.bgpcep</groupId>
<artifactId>features-bgp</artifactId>
<classifier>features</classifier>
<version>${bgpcep.version}</version>
<type>xml</type>
</dependency>

and changed protocols-config.xml(in the attachment).

When we start our feature and there is an error in bgp:
