Description
Define the role of the routing instance in a Layer 2 Wholesale network.
Options
access—Defines the connectivity
role of the routing instance in a Layer 2 Wholesale network as an
access routing instance. When defined for this role, the same process
occurs as in a Layer 3 Wholesale network—when the first packet
is received from a given client, authentication for the client initiates
with an external entity (for example, RADIUS). If authentication is
successful, a logical interface is created with the appropriate outer
and inner VLAN tags for that client.
nni—Defines the connectivity role of the routing
instance in a Layer 2 Wholesale network as a network to network interface
(NNI) routing instance. When defined for this role, only outer VLAN
tags are learned. In addition, when the NNI routing instance receives
a response from the ISP, the packets are forwarded to the appropriate
client, provided the packet has the same two tags that were verified
during authentication.
If you connect an access node or MSAN device to a router
participating in the Layer 2 Wholesale network in an NNI role, you
must create a new routing instance of type l2backhaul-vpn with an instance role of type access for that connection.
