Basic knowledge of MPLS technology, IGX and router operation is assumed.
Manuals are to be consulted for an exhaustive equipment and command reference.
This section features Configuration samples for each part of the network. What's more, a hierarchical OSPF implementation has been chosen here, as it is commonly found in Service Provider Networks. These LSR interfaces become virtual interfaces of the LSC router and behave very much like any other router interface. Configure VSI-controlled ATM ports or trunks. VSI-controlled virtual trunks cannot carry Autoroute traffic, which results in the inability to add the trunk after enabling VSI, or the inability to enable VSI on a trunk that's been added.
