Troubleshooting Ipv6 Basics Configuration; Symptom; Solution - HPE FlexNetwork HSR6800 Configuration Manual

Configuration procedure
1. Configure IPv6 addresses for the interfaces as shown in
can reach the L3VE interface of Router B. (Details not shown.)
2. Configure IPv6 ND suppression:
# Create a cross-connect group named vpna.
<RouterA> syatem-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.
[RouterA-xcg-vpna-svc] display ipv6 nd suppression xconnect-group
IPv6 address
2001::1
2001::3
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.

output interface is correct and the interface is up.
2. Use the debugging ipv6 packet command in user view to enable the debugging for IPv6
packets to locate the fault.
