Re: Can I do this in EVPN? (Multihome to more different CEs)

Hi Simon, This looks like an interesting project. What are you ultimately trying to achieve? Stretching an Ethernet segment between sites shouldn't be the first choice, but I imagine you're having to deal with some legacy use case and your hands are tied. I'm a little curious on what that might

You should be able to setup a VPLS between 3 (or more) devices. Something like this -- Example: VFI on a PE Device The following example shows a virtual forwarding instance (VFI) configuration: Device(config)# l2 vfi vfi110 manual Device(config-vfi)# vpn id 110 Device(config-vfi)# neighbor
