using weaveworks/net-plugin in swarm mode

I am using docker in swarm mode. I use weaveworks/net-plugin and enable multicast as follows
I did the following step to deply my service in swarm mode with cote and weaveworks/net-plugin.

1. step one: i run the following commands in each node

```
docker plugin install weaveworks/net-plugin:latest_release &&
docker plugin disable weaveworks/net-plugin:latest_release &&
docker plugin set weaveworks/net-plugin:latest_release WEAVE_MULTICAST=1 &&
docker plugin enable weaveworks/net-plugin:latest_release
```

1. step two: I ran my compose file this my file

```
version: '3'

networks:
cote:
# driver: "overlay"
driver: "weaveworks/net-plugin:latest_release"
services:
api-service:
image: aaami1ster/taxi:base
deploy:
replicas: 1
restart_policy:
condition: on-failure
environment:
- NODE_ENV=production
- TZ=Africa/Cairo
networks:
- cote
command: node api-service/bin/www
ports:
- "3100:3100"
my-service:
image: aaami1ster/taxi:base
deploy:
replicas: 1
restart_policy:
condition: on-failure
environment:
- NODE_ENV=production
- TZ=Africa/Cairo
networks:
- cote
command: node my-service/app.js
```
I enable multicast, but still not work. what am I missing?????
