Caution:
In VLL, you can configure only one virtual circuit for each VLAN interface.
VLL supports VLAN interfaces only. When you configure a VLL on a VLAN interface,
data is encapsulated as Ethernet packets by default.
You must use cards with the suffix CA (such as LSB2FT48CA) for the P devices and
PE devices at the access sides of CCC public/private network.
You can configure only one VLAN on the access side of each VPN private network.
Each VLAN can contain only one interface, and IGMP and IGMP Snooping cannot
be enabled in any of the VLANs configured on the interface. If IGMP and IGMP
Snooping are enabled in some of the VLANs configured on the interface, IGMP
packets cannot be transparently transmitted in the VPN.
You must configure two static LSPs for each remote CCC connection. Two CCC
connections cannot share one static LSP.
A static LSP used by a remote CCC connection cannot be used for other purposes
(such as carrying IP packets and BGP/MPLS VPN packets). When you configure a
static LSP for a CCC connection, the next hop must be the IP address from which
the ARP packets are learnt.
CCC does not support multiport access of private network.

Remarks
Required. Two types of
CCC connections exist:
local CCC connection and
remote CCC connection.
A local CCC connection is
established between two
local CEs. It can be
switched directly by the
PE without being
configured a static LSP. A
remote CCC connection is
established between the
local CE and a remote
CE. The two CEs are
attached to different PEs.
In this case, you need to
configure two static LSPs
for bidirectional packets
transmitted between the
two PEs.
