Configuration Guide - IP Routing
After you configure the association between the IPv6 direct route and PW status, when the L3VE
interface on AGG1 goes from Down to Up, the cost of the IPv6 direct route between the CSG
and AGG1 increases. In this case, RSGs do not preferentially select routes advertised by AGG1
and downstream traffic still travels along LinkB. After PW1 between the CSG and AGG1
becomes the primary PW, the cost of the IPv6 direct route between the CSG and AGG1 is restored
to the default value 0. Then, RSGs preferentially select routes advertised by AGG1 and
downstream traffic is switched over to LinkA. At this time, AGG1 has learned the MAC
addresses of the base stations, downstream traffic loss will be reduced after the configuration.
Pre-configuration Tasks
Before configuring the association between the IPv6 direct route and PW status, complete the
following tasks:
l
Data Preparation
To configure the association between the IPv6 direct route and PW status, you need the following
data.
No.

Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
interface virtual-ethernet interface-number
A VE interface is created and the VE interface view is displayed.
Step 3 Run:
ve-group ve-group-id l3-access
The VE interface is configured as an L3VE interface and bound to a VE group.
Step 4 Run:
quit
Return to the system view.
Step 5 Run:
interface virtual-ethernet interface-number.subinterface-number
Issue 02 (2014-09-30)
Configuring link-layer protocol parameters and IP addresses for interfaces to ensure that
the link layer protocol of each interface is Up
Data
Cost of the L3VE interface's direct route to the CSG
NOTE
The Layer 2 Virtual Private Network (L2VPN) can access the L3VPN only if the Layer 2 Virtual Ethernet
(L2VE) and L3VE interfaces are bound to the same VE group and reside on the same board.
