Ericsson Router 6672 Configuration ((install)) -

Mastering the Ericsson Router 6672: A Comprehensive Configuration Guide Introduction In the rapidly evolving landscape of IP transport and mobile backhaul, the Ericsson Router 6672 (often referred to as the R6672 ) stands as a workhorse. Part of the Ericsson Router 6000 series, this device is engineered for high-capacity aggregation sites, small core nodes, and edge routing in 4G/LTE and 5G transport networks. Built on the robust IPOS (IP Operating System) , the R6672 bridges the gap between legacy SDH/SONET networks and modern, packet-based infrastructures. However, for network engineers new to the Ericsson ecosystem, the CLI structure can appear daunting. This guide demystifies the R6672, walking you from initial bootstrapping to advanced routing and MPLS configuration.

Part 1: Hardware Overview and Prerequisites Before touching the CLI, understanding the physical chassis is crucial. Key Specifications

Form Factor: 2RU (2 Rack Units) Switching Capacity: Up to 120 Gbps Interface Types: 10/100/1000Base-T, 1GE SFP, 10GE SFP+, and 10GE LAN/WAN PHY. Power: Dual redundant -48V DC or optional AC. Typical Use Case: Cell site gateway, small aggregation ring node.

What You’ll Need

Console Cable: RJ45 to DB9 (or USB-to-serial adapter). Terminal Emulator: PuTTY, SecureCRT, or Minicom (Settings: 9600 baud, 8 data bits, 1 stop bit, no parity). Management IP: A laptop with an Ethernet port for the dedicated MGMT port. Software Image: The latest IPOS .bin file (obtained from Ericsson support).

Part 2: Initial Access and Bootstrapping Step 1: Console Connection Connect your console cable to the CONSOLE port on the front panel. Power on the unit. You will see the boot sequence. Wait for the login prompt. Step 2: Default Login login: admin Password: admin

(Note: On first boot, you will be forced to change the password.) Step 3: Entering Configuration Mode Unlike Juniper’s configure or Cisco’s config t , IPOS uses a hierarchical structure: R6672> enable R6672# configure terminal R6672(config)# ericsson router 6672 configuration

Step 4: Basic System Naming and Banner Set a hostname for easy identification: R6672(config)# hostname AGG-R6672-London AGG-R6672-London(config)# banner motd "Authorized Access Only - 5G Transport Node"

Step 5: Setting the System Clock For accurate logging and certificate validation: AGG-R6672-London(config)# clock timezone UTC 0 AGG-R6672-London(config)# ntp server 10.10.1.1 prefer AGG-R6672-London(config)# ntp enable

Part 3: Management Plane Configuration The dedicated MGMT port (eth0) is separate from the data plane. Configuring the Management Interface AGG-R6672-London(config)# interface mgmt eth0 AGG-R6672-London(config-if-mgmt)# ip address 192.168.1.100/24 AGG-R6672-London(config-if-mgmt)# ip default-gateway 192.168.1.1 AGG-R6672-London(config-if-mgmt)# no shutdown AGG-R6672-London(config-if-mgmt)# exit However, for network engineers new to the Ericsson

Enabling SSH and Disabling Telnet Security is paramount. Generate an RSA key and enable SSHv2: AGG-R6672-London(config)# crypto key generate rsa AGG-R6672-London(config)# ip ssh version 2 AGG-R6672-London(config)# ip ssh enable AGG-R6672-London(config)# no telnet server enable
