Configuring Inter-As 6Pe Optionb - Huawei Quidway NetEngine80E Configuration Manual

HUAWEI NetEngine80E/40E Router
Configuration Guide - IP Routing
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp { as-number-plain | as-number-dot }
The BGP view is displayed.
Step 3 Run:
peer ipv4-address as-number { as-number-plain | as-number-dot }
The IP address and AS number of the 6PE peer are specified.
Step 4 Run:
ipv6-family unicast
The IPv6 unicast address family view is displayed.
Step 5 Run:
peer ipv4-address enable
The 6PE peer relationship is enabled in the IPv6 unicast address family view.
Step 6 Run:
peer ipv4-address label-route-capability
The function to send labeled routes is enabled.
Step 7 (Optional) Run:
apply-label explicit-null
6PE routes to be sent to the same 6PE peer are configured to share the same explicit null label.
By default, each 6PE route is assigned a label. The number of required labels is proportionate
to the number of 6PE routes to be sent to the 6PE peer. If a large number of 6PE routes are to
be sent, a large number of labels are required.
After 6PE routes to be sent to the same 6PE peer are configured to share the same explicit null
label, all the 6PE routes to be sent to 6PE peers share the same explicit null label 2. The number
of required labels is irrelevant to the number of 6PE routes to be sent. This configuration saves
label resources on 6PE devices.

9.14.3 Configuring Inter-AS 6PE OptionB

Inter-AS IPv6 Provider Edge (6PE) OptionB enables separate IPv6 networks that connect to
different ASs to communicate over an inter-AS OptionB network.
Issue 02 (2014-09-30)
NOTE
If a 6PE peer relationship has been established, running this command will trigger PEs to re-allocate labels
and cause temporary packet loss.
