Hardware configuration
The following sections describe the hardware configurations.
Configuring line cards
Define line card types explicitly based on the system type.

Configuring ports and interfaces
Configure the physical port first, followed by an interface with an IPv4 or IPv6 address.
Each port is considered a connector that supports breakout. Configure the connector with the breakout type so that the appropriate ports are created and can be configured.
Configuring the connector breakout type
The following example displays the configuration of a connector breakout. The default port MTU value is 9212.
configure port 1/1/c1 admin-state enable
configure port 1/1/c1 connector { breakout c1-100g }
configure port 1/1/c1/1 admin-state enable
configure port 1/1/c1/1 description “To Peering LAN"
Configuring the router interface
The interface is provided a name, an IP address, and is associated with a physical port as shown in the following example.
configure router "Base" interface "To-Peering-LAN" port 1/1/c1/1
configure router "Base" interface "To-Peering-LAN" ipv4 { primary address 192.168.0.1 prefix-length 24 }
configure router "Base" interface "To-Peering-LAN" ipv6 { address 2001:a8::4 prefix-length 124 }
Configuring the system interface
The system interface is the router's loopback interface (like lo0 or loopback0) and is configured as shown in the following example.
configure router "Base" interface "system" ipv4 { primary address 10.0.0.1 prefix-length 32 }
configure router "Base" interface "system" ipv6 { address 2001:1::101 prefix-length 128 }
