Ipv6 Nd Suppression Configuration Example - HP FlexNetwork MSR2003 Configuration Manual

To ping a link-local address, use the –i parameter to specify an interface for the link-local address.
[RouterB] ping ipv6 -c 1 3001::1
Ping6(56 data bytes) 3001::2 --> 3001::1, press CTRL_C to break
56 bytes from 3001::1, icmp_seq=0 hlim=64 time=4.404 ms
--- Ping6 statistics for 3001::1 ---
1 packet(s) transmitted, 1 packet(s) received, 0.0% packet loss
round-trip min/avg/max/std-dev = 4.404/4.404/4.404/0.000 ms
[RouterB] ping ipv6 -c 1 2001::15B:E0EA:3524:E791
Ping6(56 data bytes) 3001::2 --> 2001::15B:E0EA:3524:E791, press CTRL_C to break
56 bytes from 2001::15B:E0EA:3524:E791, icmp_seq=0 hlim=64 time=5.404 ms
--- Ping6 statistics for 2001::15B:E0EA:3524:E791 ---
1 packet(s) transmitted, 1 packet(s) received, 0.0% packet loss
round-trip min/avg/max/std-dev = 5.404/5.404/5.404/0.000 ms
The output shows that Router B can ping Router A and the host. The host can also ping Router B and
Router A (output not shown).

IPv6 ND suppression configuration example

Network requirements
As shown in
station can reach the L3VE interface L3VE1 of Router B.
Enable IPv6 ND suppression on Router A to directly answer ND packets for Router B.

GE2/0/1
2001::1/64
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
