Router A (output not shown).
IPv6 ND suppression configuration example
Network requirements
As shown in Figure 95, the base station, Router A, and Router B are in an MPLS L2VPN. The base
station can reach the L3VE interface L3VE1 of Router B.
Enable IPv6 ND suppression on Router A to directly answer ND messages for Router B.
Figure 95 Network diagram
Configuration procedure
1. Configure IPv6 addresses for the interfaces as shown in Figure 95. Make sure the base station
can reach the L3VE interface of Router B. (Details not shown.)
2. Configure IPv6 ND suppression:
# Create a cross-connect group named vpna.
<RouterA> system-view
[RouterA] xconnect-group vpna
# Create a cross-connect named svc.
[RouterA-xcg-vpna] connection svc
# Enable IPv6 ND suppression for the cross-connect svc in cross-connect group vpna.
[RouterA-xcg-vpna-svc] ipv6 nd suppression enable
Verifying the configuration
1. On the base station, clear the ND suppression entries, and ping the L3VE interface VE-L3VPN
1 of Router B. (Details not shown.)
2. Verify that Router A has ND suppression entries for the base station and Router B.

2001::3 0023-89b7-0861 vpna svc 25
3. Enable ND debugging on Router B to verify that Router B does not receive an ND request from
the base station when the following conditions exist (details not shown):
a. Clear ND suppression entries on the base station.
b. Ping L3VE interface VE-L3VPN 1 of Router B from the base station.
