−
If incorrect ND entries exist, execute the
debugging ipv6 icmp
command to locate the
problem.
−
If the switch learns no ND entries, execute the
ipv6 neighbor
command to configure
static ND entries.
b.
Execute the
display mac-address
command to verify that the output interfaces in the MAC
address entries and ND entries are the same.
If the output interfaces are different, execute the
reset
ipv6 neighbors
command to clear
the ND entries. Then the switch can learn ND entries again.
4.
Verify that route entries are correct:
a.
Execute the
display ip routing-table
command to verify that route entries are correct.
If incorrect route entries exist, troubleshoot the protocol that learns the route entries.
b.
Execute the
display fib
command to verify that the output interfaces in the FIB entries and
route entries are the same.
If the output interfaces are not the same, execute the
reset
command to clear the route
entries. Then the switch can learn route entries again.
5.
If the problem persists, contact Hewlett Packard Enterprise Support.
