Hi,
I try to produce an situation where i have 2 orphan hosts. Each orphan host is connected to a leaf switch (for example leaf1 and leaf2). So host1(mac: 0c:89:34:41:00:00) is is connected to leaf1 and host2(mac: 00:50:79:66:68:00) to leaf2. Leaf1 and Leaf2 form an vpc domain. Both hosts are connected to vlan8 as an access port.
The problem i encounter is that host1 is not able to ping host2. I see that all mac's are learned on both leaf switches. When i try to monitor traffic within gns3 i see arp responses, but it seems like the pc connected to the primary switch learn's the mac of host2, but host2 not of host1.
I know this isn't a best practise, but i want to know if it's possible and if not why it's not possible.
vpc config:
vpc domain 101
peer-switch
peer-keepalive destination 10.10.10.62 source 10.10.10.63 vrf default
virtual peer-link destination 10.10.10.62 source 10.10.10.63 dscp 56
peer-gateway
ipv6 nd synchronize
ip arp synchronize
interface port-channel999
vpc peer-link
