Choly, I removed the "ip flow egress and now work". Thanks a lot.
But i still have one more question,
Before, I had the below configuration on my router A LAN interface.
interface GigabitEthernet0/1
ip address 10.x.x.x 255.255.x.x
no ip redirects
ip flow ingress
ip flow egress
And I added both LAN and WAN interface of router A onto Solarwinds.
So , what if I keep the configuration, and removed the WAN interface of router A on Solarwinds, the duplicate flows issue would not happen , correct ?
or it doesn't matter the WAN interface here or not, once you configure " ip flow egress" on the interface, duplicate flows issue would happen?
