I have a PA with two switches connected to the PA via L2 interface, in trunk. The same switches have a trunk between them.
So far so good, STP works and the network is stable. If one of the links between switch and PA falls (exemple PA to SW1) everything works too, all the traffic is redirect to PA via SW2, but as soon as link is became ok again, the Palo Alto ARP table does not refresh the Management VLAN and PA continues to think that the sw1 IP is seen by sw2.
Has anyone felt this behavior?
Hi @DiogoFG ,
It looks like a STP design issue. A say "design" because STP is working, just not as you expected.
