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 172.16.10.2 4 encapsulation mpls Device(config-vfi)# neighbor 10.16.33.33 encapsulation mpls Device(config-vfi)# neighbor 198.51.100.44 encapsulation mpls Device(config-vfi)# bridge-domain 100 Device(config-vfi)# end The following example shows a VFI configuration for a hub-and-spoke configuration: Device(config)# l2 vfi VPLSA manual Device(config-vfi)# vpn id 110 Device(config-vfi)# neighbor 10.9.9.9 encapsulation mpls Device(config-vfi)# neighbor 192.0.2.12 encapsulation mpls Device(config-vfi)# neighbor 203.0.113.4 encapsulation mpls no-split-horizon Device(config-vfi)# bridge-domain 100 Device(config-vfi)# end -----Original Message----- From: "Simon Lockhart" <simon@slimey.org> Sent: Thursday, February 9, 2023 2:47am To: nanog@nanog.org Subject: Can I do this in EVPN? (Multihome to more different CEs) All, I have a bit of a networking design challenge, and I thing EVPN is the right answer, but despite spending the last week reading loads of resources about it, I can't quite get my head around one aspect. I'm trying to genericise the design a bit here, but what I've got is... I have multiple layer two broadcast domains that I need to link together over a layer 3 network. The broadcast domains consist of multiple switches carrying multiple vlans spanning multiple locations (think of it like a customer campus network). I need to interconnect with each broadcast domain in two different locations. (so two PEs to two CEs), and link it back to a datacentre in another city. In the simple case, using EVPN, I see that I can run active-standby multihoming, configuring one ESI for the customer campus network. If one of my PEs fails, or one of the customer CEs fails, then EVPN will fail over to the other link. However, the failure scenario I need to deal with is if a layer two link fails between two locations within the customer campus, the two halves of the now split broadcast domain still need to be able to communicate with the datacentre (but do not need to be able to communicate with each other). Every example I can see for EVPN shows multihoming to a single CE, and I can't find anywhere an example which deals with a "split" ES. Is there a solution to this problem? Many thanks in advance, Simon
