L2 Connectivity
A logical connectivity between L2 of two control plane protocol
stack enables communications between the two functional
entities. The encapsulation of IP packets between the two
functional entities relies on the connectivity type, e.g. GRE
tunnel. The seal of the encapsulated packet contains address
information, which ensures that the packet can be sent to the
entities. The encapsulation of IP packets between the two
functional entities relies on the connectivity type, e.g. GRE
tunnel. The seal of the encapsulated packet contains address
information, which ensures that the packet can be sent to the
correct physical entity.
