Configuring An Ac - HP HPE FlexNetwork MSR Router Series Configuration Manual

Configuring an AC

An AC can be one of the following types on a PE:
•
Layer 3 Ethernet interface—Transparently forwards received packets to the bound VSI.
•
Layer 3 Ethernet subinterface—Forwards received packets to the bound VSI. In this mode,
VLANs are unique on a per-interface basis rather than on a per-device basis.
•
VLAN interface—Forwards all packets received from the VLAN to the bound VSI. In this mode,
VLANs are globally unique.
NOTE:
When VLANs are globally unique, packets with the same VLAN ID are forwarded by the same VSI
regardless of the receiving interfaces. If VLANs are unique on a per interface basis, packets with the
same VLAN ID from different interfaces can be forwarded by different VSIs.
To create a Layer 2 link between a PE and a CE, configure the AC interface that connects the PE to
the CE.
An AC interface can be a Layer 3 Ethernet interface (including physical Layer 3 Ethernet interface,
Layer 3 virtual Ethernet interface, and VE-L2VPN interface), VLAN interface, or Layer 3 Ethernet
subinterface.
For more information about Ethernet interfaces, see Interface Configuration Guide. For more
information about Layer 3 virtual Ethernet interfaces, see Layer 2—WAN Configuration Guide. For
more information about VE-L2VPN interfaces, see
backbone." For more information about VLAN interfaces, see Layer 2—LAN Switching Configuration
Guide.
Configuring a VSI
Step
1. Enter system view.
2. Create a VSI and enter VSI
view.
3. (Optional.) Configure a
description for the VSI.
4. (Optional.) Set the default
PW ID for the VSI.
5. Set an MTU for the VSI.
6. (Optional.) Enable the VSI.

Remarks
N/A
By default, no VSI is created.
If you specify the hub-spoke keyword
for a VSI, the VSI supports the
hub-spoke network model.
By default, no description is configured
for a VSI.
By default, no default PW ID is
configured for the VSI.
By default, the MTU of a VSI is 1500
bytes.
By default, a VSI is enabled.
