# VPLS Platform Considerations

VPLS is supported on all E Series routers.

- Module Requirements
- Interface Specifiers

## Module Requirements

You can configure VPLS network interfaces on all E Series module combinations that support transparent bridging. The VPLS virtual core interface can exist on all E Series module combinations that support MPLS tunnels.

For information about the modules that support VPLS network interfaces and VPLS virtual core interfaces on ERX14xx models, ERX7xx models, and ERX310 Braoadband Services Router:

- See ERX Module Guide, Table 1, Module Combinations for detailed module specifications.
- See ERX Module Guide, Appendix A, Module Protocol Support for information about the modules that support VPLS network interfaces and VPLS virtual core interfaces.

For information about the modules that support VPLS network interfaces and VPLS virtual core interfaces on E120 and E320 Broadband Services Routers:

- See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module specifications.
- See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information about the modules that support VPLS network interfaces and VPLS virtual core interfaces.

## Interface Specifiers

The configuration task examples in this chapter use the slot/port[.subinterface ] format to specify the physical interface on which to configure a VPLS network interface. However, the interface specifier format that you use depends on the router that you are using.

For ERX7xx models, ERX14xx models, and ERX310 routers, use the slot/port[.subinterface ] format. For example, the following command specifies Fast Ethernet subinterface 6 on port 2 of the I/O module installed in slot 3 of an ERX7xx model, ERX14xx model, or ERX310 router.

host1(config)#interface fastEthernet 3/2.6

For E120 and E320 routers, use the slot/adapter/port[.subinterface ] format, which includes an identifier for the bay in which the I/O adapter (IOA) resides. In the software, the upper IOA bay is identified as adapter 0; the lower IOA bay is identified as adapter 1. For example, the following command specifies Gigabit Ethernet subinterface 20 on port 1 of the IOA installed in the upper adapter bay (adapter 0) of slot 4 in an E320 router.

host1(config)#interface gigabitEthernet 4/0/1.20
