Hi,
I would need help with vpp IPv6 neighbor unreachability detection in vpp.
I have a running vpp instance. Vpp has an interface with ip 2001::3, which is
connected to linux network interface with ip 2001::5.
When I ping 2001::5 from vpp, neighbor solicitation and advertisement runs and
I can see a record in neighbor table.
vpp# show ip6 neighbors
Time Address Flags Link layer
Interface
23973.4355 2001::5 D 08:00:27:ba:84:9e
GigabitEthernet0/9/0
Then I down linux interface 2001::5. When I try ping 2001::5 in vpp, no reply
is received, but neighbor entry is still present in the table when I run show
ip6 neighbors.
When I try it other way round (down vpp's 2001::3 interface, ping6 2001:3 from
linux) ping receive no reply and neighbor entry is marked as FAILED.
$ip -6 neigh
2001::3 dev eth2 FAILED
Is there some way how to get such unreachability info also from vpp?
Thanks for help
Andrej
