SIGNALING IP ADDRESS MOBILITY IN ETHERNET VIRTUAL PRIVATE NETWORKS

摘要

In some examples, a provider edge device provides L2 virtual bridge connectivity for at least one customer network using an EVPN instance and L3 routing using an IRB interface that is a L3 routing interface assigned to the EVPN instance; the provider edge device obtains an indication of a new binding for an endpoint device of the at least one customer network, the new binding comprising a first L2 address and a L3 address that are assigned to the endpoint device; and the provider edge device outputs, in response to determining the provider edge device stores a prior binding for the endpoint device of a second L2 address and the L3 address that are assigned to the endpoint device, an EVPN route comprising an indication of the new binding and an indication the new binding is an updated binding of the prior binding for the endpoint device.
