Our client has existing distribution HP switch which is just layer2 switch has a configuration in VLAN Default 192.168.123.10/24 for the managing of their switch.
We are implementing new core switch x670 which I configured our VLAN default to 192.168.122.1 and has a VLAN 123 which is 192.168.123.1
Our gateway/router is 192.168.3.254
Laptop from HP switch can ping the core and router, but laptop from core cannot ping the HP switch default IP and laptop IP.
How to resolve this?
Is there any configuration need?
I will try tomorrow traceroute and arp from core to hp switch.
Thanks and Best Regards,
