Interoperating with Other Vendors

This section presents notes on interoperating with other vendors in a draft-rosen multicast VPN.

If your Juniper Networks routers must to interoperate with other vendors’ routers, take one of these approaches:

• Configure the other vendors’ routers to interoperate with the Juniper Networks routers.
• Configure the Juniper Networks routers to interoperate with the other vendors’ routers.

If you are configuring the other vendors’ routers to operate like Juniper Networks routers, verify the following:

• All provider tunnels use the same group address.
• All routers are configured with the same IP address for the lo0.n interface in the routing instance as the IP address for the lo0.0 interface in the master instance.

By default the Junos OS attaches a route target to multicast distribution tree (MDT) subsequent address family identifier (SAFI) network layer reachability information (NLRI) route advertisements. Some vendors do not support attaching route targets to the MDT-SAFI route advertisements.

For interoperability with these vendors, the Junos OS allows importing of MDT-SAFI route advertisements without a route target being attached. The MDT-SAFI is imported if the MDT default address in the MDT-SAFI prefix matches the MDT default address configured within the routing instance.

For more information about configuring the MDT default address to interoperate with other vendors’ routers, see and Example: Configuring Draft Rosen Interoperability and a VPN Tunnel Source and Example: Configuring Source-Specific Multicast for Draft-Rosen Multicast VPNs.
