When access layer switch has multiple VLAN，the access layer switch is just a layer 2 device. It should have two-node cluster hot backup to make sure that multiple VLAN uplink redundancy. Commonly, every VLAN need two lines to connect to the two devices. It will use a device port and multiple VLAN will use multiple ports.

No matter how much VLAN ,open how much VRRP, it just need two lines.
