S1.
POS-05: IPv6 Neighbor Discovery Cache Inspection#
On R1 privileged EXEC mode:
R1#show ipv6 neighbors
IPv6 Address Age Link-layer Addr State Interface
2001:DB8:ACAD:1:200:CFF:FE6A:EA59 0 0000.0C6A.EA59 REACH Gig0/0/0

R1(config)#no ipv6 unicast-routing
R1(config)#end
R1#show ipv6 interface GigabitEthernet0/0/0
GigabitEthernet0/0/0 is up, line protocol is up
IPv6 is enabled, link-local address is FE80::1
No Virtual link-local address(es):
Global unicast address(es):
2001:DB8:ACAD:1::1, subnet is 2001:DB8:ACAD:1::/64
Joined group address(es):
FF02::1:FF00:1
MTU is 1500 bytes
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ICMP unreachables are sent
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
- Verification criteria: Router leaves
FF02::2(all-routers) multicast group; RA timers and autoconfig flags are suppressed.
NEG-02: Unresolved Neighbor Solicitation to Non-Existent Target#
On R1 privileged EXEC mode:
R1#ping 2001:db8:acad:1::999
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:db8:acad:1::999, timeout is 2 seconds:
.....
Success rate is 0 percent (0/5)
- Verification criteria: Neighbor solicitation attempts go unacknowledged, leading to 0% ICMP delivery rate.
