How is it possible to detect/locate/discover a duplicate IP address in a network (LAN)?
I have recently found in one of my LAN (remote site) that a switch has the same address as the virtual VRRP (adress of my two WAN devices). I had often many connectivity issues because of this conflict but when i connect to WAN devices i ping the shared address without any problem, thus for me no problem with the adress.
- How can I know if the adress match the VRRP or the switch ?
- Does someone know some cisco advanced command to see this in cisco routers or switchs ?
- is the show mac-address-table can give me the two mac if any conflict occurs ? so i can locate the port.
- from my switch, is there any command to have all ip address of devices connected in LAN ? or mac-addresses ?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
