Configuring Input SCU on the vt Interface of the Egress PE Router
To enable SCU in a Layer 3 VPN, configure source
class usage on the virtual loopback tunnel (vt) interface
of the egress PE router that is either configured for or equipped
with a Tunnel PIC. The interface is equivalent to the inbound SCU
interface, so use the input
statement at the [edit
interfaces vt-interface-number unit 0 family
inet accounting source-class-usage]
hierarchy level:
[edit] interfaces { vt-0/3/0 { unit 0 { family inet { accounting { source-class-usage { input; } } } } } }
