Description

Select family as protocol primary. In some customer use cases, CPE devices have reachability to multiple BNG routers for load sharing. The CPE’s DHCP client broadcasts a DHCP protocol handshake to the reachable routers; more than one router may respond. In a DHCP dual-stack environment, the DHCPv4 and DHCPv6 protocol handshakes are independent of each other, meaning that each arm of the subscriber session could connect to a different router. You can avoid this situation by specify the primary protocol. For a given dual-stack subscriber, this configuration causes the rejection of any binding attempt from the secondary address family client when a binding is not currently active for the primary protocol family. If bindings are currently active for both arms when the primary protocol family binding is released or deleted, then the binding for the secondary address family is also torn down.

Options

inet

INET family has protocol primary behavior.

inet6

INET6 family has protocol primary behavior.
