Figure 2-11. 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.
