Choose two
  • A set vlans default vlan-id 20
  • B set vlans vlan-10 13-interface irb.10
  • C set vlans vlan-20 13-interface irb.20
  • D set vlans default vlan-id 10
Explanation

Juniper inter-VLAN routing uses an IRB interface as the Layer 3 interface for each VLAN. Each VLAN must include an l3-interface reference to its matching configured IRB unit: VLAN 10 to irb.10 and VLAN 20 to irb.20. The IP addresses on those IRB units provide routing between the two directly connected subnets.
