Hi
consider an all-active multihomed scenario (single CE with multiple PE). in the section 8.5 of the RFC it says that the CE will treat links to the PEs as a link aggregation group.
Is this a LAG like in a LACP bond? I'm assuming the PEs won't support any link aggregation protocols because they would need to have some shared control-plane state like in an MLAG or vPC? How is it done in practice, using static LAGs?
The relevant section from the RFC:
Note that a CE always sends packets belonging to a specific flow using a single link towards a PE. For instance, if the CE is a host, then, as mentioned earlier, the host treats the multiple links that it uses to reach the PEs as a Link Aggregation Group (LAG). The CE employs a local hashing function to map traffic flows onto links in the LAG. If a bridged network is multihomed to more than one PE in an EVPN network via switches, then the support of All-Active redundancy mode requires the bridged network to be connected to two or more PEs using a LAG.
