Juniper ACX2000 Configuration Guide

Configuring Precision Time Protocol Over Integrated Routing and Bridging
Junos OS for ACX Series router supports configuring precision time protocol (PTP) over
integrated routing and bridging (IRB). You can configure a boundary clock node with PTP
(IPv4) over IRB in a master-only mode across single or multiple IRB logical interfaces.
To configure Precision Time Protocol (PTP) over IRB:
1. Configure physical interfaces with Layer 2 encapsulation and create logical units with
VLANs.
[edit interfaces ge-0/2/1]
flexible-vlan-tagging;
native-vlan-id 130;
encapsulation flexible-ethernet-services;
unit 615 {
encapsulation vlan-bridge;
vlan-id 615;
}
[edit interfaces ge-0/0/3]
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 615 {
encapsulation vlan-bridge;
vlan-id 615;
}
[edit interfaces ge-0/1/2]
flexible-vlan-tagging;
encapsulation flexible-ethernet-services;
unit 615 {
encapsulation vlan-bridge;
vlan-id 615;
}
[edit interfaces ge-0/2/0]
flexible-vlan-tagging;
native-vlan-id 130;
encapsulation flexible-ethernet-services;
2. Configure physical interfaces on a bridge domain.
[edit bridge-domains]
bd-615 {
vlan-id 615;
interface ge-0/1/2.615;
interface ge-0/2/0.615;
interface ge-0/2/1.615;
interface ge-0/0/3.615;
}
3. Configure a routing instance for the bridge domain where physical interfaces are
members of the bridge domain.
