Feature Description

DHCP IP Lease Reservation feature enables the DHCP to allocate an IP address dynamically when the subscriber logs into the network the first time. Then, the assigned IP address can be reserved permanently for the subscriber, which means, the same IP address is assigned every time the subscriber logs in.

Feature Description


Note

This feature is Network Services Orchestrator (NSO) integrated.

To provide redundancy for the subscriber sessions, cnBNG supports Geographical Redundancy across multiple User Planes (UPs), without having any L1 or L 2 connectivity between them. The UPs may be located in multiple geographical locations, and they have L3 connectivity over a shared core network through IP or MPLS routing.

Geo redundancy for subscribers is delivered by transferring the relevant session state from primary UP to subordinate UP which can then help in failover (FO) or planned switchover (SO) of sessions from one UP to another. Subscriber Redundancy Group (SRG) which is a set of access-interface (or a single access-interface) is introduced in cnBNG, and all subscribers in an SRG would FO or SO as a group.

Geo redundancy feature is currently supported for IPoE DHCP-triggered (IPv4, IPv6 and dual-stack) sessions.
