H3C Dual Layer Configuration

Summary

Dual Layer Networking prepared to ensure LAN’s traffic flow among themselves without reaching Antikor v2.
If any client which in a LAN wants to reach an external address, it shall get service from Antikor v2 otherwise it wants to reach an internal but different LAN, it will suffice to get service from backbone switch.

Testing

When we run traceroute from PC 2 to PC 0, we saw that the traffic did not go as far as Antikor v2 and turn around to right destination Network from Backbone Switch.

Please follow Antikor v2 Dual Layer Configurations Manual for required settings on the Antikor v2 side.

Troubleshooting

Executing Command	Error Message	Solution Proposal
`ping 10.2.1.2`	— Ping statistics for 10.0.0.1 — 5 packets transmitted, 0 packets received, 100.0% packet loss	Check the status of the ports.
		Review VLAN settings.
