You can configure a MX240 router or MX480 router as a member router in an MX Series Virtual Chassis that contains a MX2010 or MX2020 member router. In earlier releases, MX2010 routers and MX2020 routers could only interoperate with MX960 routers.
The following member router combinations are introduced for a two-member Virtual Chassis configuration:
| Product / Application | Software | Introduced Release |
|---|---|---|
| MX2010 | Junos OS | 16.1R1 |
| MX2020 | Junos OS | 16.1R1 |
