Hello,
I have two Nexus switches in a lab environment with a vPC configured, the down stream is connected to another switch (vPC) and the up stream is connected to firewalls working in active-standby mode with OSPF configured with vPC peer switches.
The topology looks like the below;
The configuration of vPC on both switches is as the below;
vpc domain 10
peer-switch
peer-keepalive destination 10.10.10.2 source 10.10.10.1 vrf vpcvrf
delay restore 60
peer-gateway
layer3 peer-router
auto-recovery
ip arp synchronize
interface port-channel1
vpc peer-link
interface port-channel2
vpc 1
Spanning tree configuration on both switches;
spanning-tree vlan 1,30,40 priority 24576
spanning-tree vlan 2-29,31-39,41-3967 priority 0
interface port-channel1
spanning-tree port type network
The issue is;
I'm getting this syslog message "STP-2-DISPUTE_DETECTED" when I'm reloading one of the vPC peers to figure out the behavior of the vPC in this case, and the behavior was receiving the mentioned syslog message and a traffic disruption occur while forming the vPC with the peer switch.
Could you please advice if the configuration is correct? Any enhancement needs to be implemented? Is the topology correct?
Regards,
