ge-0/0/4 added to logical system LR3, in order to connect external device (in this case arm64 sbc) we will need dhcp server. Dhcp pool will be configured for /30 … will provide single ip address via dhcp 🙂
Configure dhcp-server
# configure ge-0/0/4 for dhcp-server
set system services dhcp-local-server group dhcp interface ge-0/0/4
# configure dhcp server pool
set access address-assignment pool dhcp family inet network 10.0.4.0/30
set access address-assignment pool dhcp family inet range dhcp low 10.0.4.2
set access address-assignment pool dhcp family inet range dhcp high 10.0.4.2
# configure dhcp server attributes
set access address-assignment pool dhcp family inet dhcp-attributes name-server 8.8.8.8
set access address-assignment pool dhcp family inet dhcp-attributes name-server 8.8.4.4
set access address-assignment pool dhcp family inet dhcp-attributes router 10.0.4.1Validation
# connect device with dhcp client to port ge-0/0/4 and check local dhcp server
