Kompella Mpls Vll Configuration Example (1) - H3C S9500 series Operation Manual

Operation Manual – MPLS VLL
H3C S9500 Series Routing Switches
Caution:
You can only change the CE range to a number larger than the existing one. For
example, you can change a CE range from 10 to 20, rather than from 10 to 5. The
only way to change a CE range to a smaller number is to remove the CE and create
a new one.
You must use cards with suffix CA (such as LSB2FT48CA) on the public/private
network access side when configuring Kompella MPLS VLL.
VLL supports single port or multiport access private VLANs, while the Kompella VLL
local connection does not support multiport access.
Multiport access enabled Kompella VLL does not support VLANs with intermixing
ports or aggregated ports.
Only one VLAN is allowed on the access side of each VPN private network. Each
VLAN can contain only one interface. IGMP and IGMP Snooping cannot be enabled
in any of the VLANs configured on the interface. If IGMP and IGMP Snooping are
enabled on some of the VLANs configured on the interface, IGMP packets cannot
be transparently transmitted in the VPN.
In Kompella MPLS VLL, the encapsulation type on the access side of each private
network can be Ethernet access and VLAN access. Ethernet access is the default
type. If you configure the encapsulation type as Ethernet access, the port link type in
a private network VLAN is Access type; if you configure the encapsulation type as
VLAN access, the port link type in a private network VLAN is Trunk type. It is not
recommended to use Hybrid type as the port link type in a private network VLAN.
The user access modes of the instance in all peer PEs must be consistent.
In Kompella mode, VPNs are established in the entire SP network. In each VPN, a
CE is assigned a CE ID, which must be unique in the VPN. In a VPN, connections
cannot be established between CEs with the same CE IDs. In this case, You need to
remove the configurations of the CEs with the same CE IDs and configure CE IDs
for these CEs again to establish the connections.
The MTU configured here has no effect on the actual MTU on the link.
