Dynamic Host Configuration Protocol

  • DHCPv4 and DHCPv6 relay agent support for MC-LAG (ACX7100-32C and ACX7100-48L)—Starting in Junos OS Evolved Release 22.2R1, DHCPv4 and DHCPv6 relay agents support multichassis link aggregation groups (MC-LAG). These DHCP relay agents are used to forward DHCP requests and replies between clients and servers when they are on different physical subnets. In this release, we support the stateless forward-only DHCP relay agent mode.

    DHCP relay agent support includes the following:

    • DHCPv4 and DHCPv6 Stateless forward-only option on Layer 3 static interfaces over MC-LAG
    • DHCPv4 and DHCPv6 Stateless forward-only option on IRB interfaces over MC-LAG
    • DHCPv4 and DHCPv6 forward-snooped-clients on dual-stack configurations
