Workflow to configure L3 VPN transport setup

Stages

Perform the following stages to configure a microwave backhaul L3 service:

1	Initialize an L3 VLAN. See To initialize an L3 VLAN ID.
2	Configure a routing instance. See To configure a System and Network interface.
3	Perform manual initialization of the MPLS protocol. See To initialize the MPLS protocol.
4	Perform manual configuration of the remote system. See To configure an MPLS interface.
Configure OSPFv2 based L3 VPN
5	Configure an OSPFv2 Router ID. See To configure OSPFv2 Router ID.
6	Configure a dynamic LSP. See Workflow to configure OSPFv2.
7	Configure an IP/MPLS service tunnel. See To configure IP/MPLS Service Tunnel.
Configure Static L3 VPN
8	Configure a static route. See To configure a static route.
9	Configure a static LSP. See To configure a static LSP.
10	Configure an SDP tunnel. See To create an SDP Tunnel.

Note: On the Manage VLAN Groups form, you can automate static routing configuration (static routes and MPLS) using the Transport Setup button and dynamic routing configuration (MPLS and OSPF) using the Dynamic Transport Setup button. Also, the Enable MPLS interfaces must be selected to enable all MPLS interfaces on the nodes involved in VLAN group. The Transport Setup button automates the initialization of MPLS, and configuration of the remote system and static routes. The Dynamic Transport Setup button automates the initiation of MPLS, configuration of the remote system, initialization of OSPF, configuration of OSPF areas, instances, interfaces, and deletes static routes on the configuration, as this is the preferred option for dynamic routing configuration.

From the Transport Setup and Dynamic Transport Setup windows, you can manage incremental or decremental changes in the network. If an L3 node is added to the network, routes will be updated on all the nodes to reflect the addition of an L3 node. Similarly, if a node is deleted from the network, routes will be deleted relevant to the deleted node.

In case of conversion of the network configuration from linear to ring topology, transport setup is not supported due to limitation from the wavence node. In this scenario, dynamic transport setup option can be used for the required configuration. The routes are based on best available path.

The Dynamic Transport Reset (removes OSPF objects) and Transport Reset (removes MPLS objects) buttons in the Manage VLAN groups window can be used to remove one or more nodes from an L3 VPN.  However this action does not delete the node from the VLAN group.
