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;
}
}
}
}
}
}
