MetroEthernet VLAN redundancy

[batangbaler]

Hi we have metro ethernet as our WAN provider and requiring as to have 2 VLANs. How are we going to configure 2 VLANs in one physical port, one is i guess primary and one is backup. Appreciate the response thanks.

I'm not sure I fully understand your requirement. I'm assuming that your router connects to their switch. If they've asked you to configure two vlans, you'd simply create two subinterfaces on the interface that connects to their switch and tag it:

int fa0/0

no ip address

int fa0/0.1520

encaps dot1q 1520

ip address

int fa0/0.2222

encaps dot1q 2222

ip address

Is this what you're looking for? I must say though, providing two vlans on a single cable isn't going to provide redundancy for your equipment.

HTH,
John
