Adding Branch Sites to an Existing WAN Link A LAN Connection Group, or LCON Group, is a set of LCONs (SVCs/PVCs) that are associated with a single Router Interface. Each LCON in a group is configured with the IP and/or IPX node address of the Router on the remote end of the LCON. Encapsulation LCONs are configured with an Encapsulation Type, which determines how the various protocols (IP, IPX, etc.) are encoded in a packet. Each SVC within the LAN Connection Group can be selected to have a different WAN encapsulation. For example, in an X.25 network, one SVC can have encapsulation Type RFC877 while another is CODEX. Mixed SVCs/PVCs Each LAN Connection Group can support mixed types of SVCs, as allowed by the network type. You can mix permanent SVCs, On Demand SVCs, and Dial On Demand SVCs. You can also have PVCs in the same LAN Connection Group as SVCs. Parallel SVCs A Parallel SVC is an LCON configured as attached to the same Router Interface as a primary SVC in the local router and the same next hop address as the primary SVC in the remote router. MTU Size All SVCs in a LAN Connection Group have the same Router MTU size, since Router MTU size is configured on a per Router Interface basis. Broadcast Information IP and IPX RIP can be enabled or disabled on any Router Interface associated with a LAN Connection Group. Vanguard Routing Model T0100-01, Revision B 2-19 Release 5.4
