Configuring VLAN Dynamic Subinterfaces

Use to route layer 2 traffic to the specified router.
For detailed information about using the mpls-relay command, see chapter Configuring
Layer 2 Services over MPLS in JunosE BGP and MPLS Configuration Guide.
Example
host1(config-if)#mpls-relay 10.10.100.2 45
Use the no version to negate this command.
See mpls-relay.
E Series routers support configuration of dynamic VLAN subinterfaces over static VLAN
major interfaces over Ethernet.
When you configure the dynamic VLAN subinterface, you can enable autodetection and
dynamic creation of the following upper-layer encapsulation types:
IP
PPPoE
NOTE: Unlike ATM, which supports dynamic upper interfaces over static ATM 1483
subinterfaces, you must configure a dynamic VLAN subinterface to enable autodetection
and dynamic creation of IP and PPPoE interfaces.
Figure 59 on page 653 shows the dynamic upper-interface columns supported by dynamic
VLAN subinterfaces, and indicates which layers in the columns are static and dynamic.
Figure 59: Dynamic Interface Columns over Dynamic VLAN Subinterfaces
Unlike ATM 1483, you can configure both IP and PPPoE over a single dynamic VLAN
subinterface (Figure 60 on page 654).
