Subscriber Services: Chassis-based DHCP redundancy

We support 1:1 redundancy for active lease queries below the limit of quantification (BLQ). This feature enhances reliability by providing redundancy for non-participating underlying subscriber interfaces, regardless of topology discovery. You can exclude interfaces without topology discovery. Use this feature on subscriber stacks and DHCP configurations and BBE and non-BBE DHCP configurations in the following scenarios:

• Subscriber management "Enabled" and "Disabled" modes.
• IP Demux and IP Demux Lite.
• Dual-stack and dual-stack single-session modes.
• Pseudowire access model PS Interfaces (L2 Circuit, EVPN VPWS, and L2VPN).
• VRRP access model for gigabit Ethernet, 10Gb Ethernet, and aggregated Ethernet interfaces.
• Non-default routing instances.
• DHCP relay and DHCP servers.
