    Hi Experts,

    I need to convert IP helper configuration from a Cisco core switch to a Juniper EX9200 switch. Can you please confirm if this configuration is correct?

    VLAN 10 mapped to irb.10 and VLAN 20 mapped to irb.20.
    Cisco Config:

    Cisco SWITCH#sh run int vlan 10 | i helper
ip helper-address 10.10.50.100
Cisco SWITCH#sh run int vlan 20 | i helper
ip helper-address 10.10.100.100
Cisco SWITCH#

    Juniper config:

    set forwarding-options dhcp-relay server-group DHCP_Server_1 10.10.50.100
set forwarding-options dhcp-relay server-group DHCP_Server_2 10.10.100.100

set forwarding-options dhcp-relay group DHCP_Group_1 active-server-group DHCP_Server_1
set forwarding-options dhcp-relay group DHCP interface irb.10

set forwarding-options dhcp-relay group DHCP_Group_2 active-server-group DHCP_Server_2
set forwarding-options dhcp-relay group DHCP interface irb.20
