Sample config below, but it needs a specific tcam profile, which you’d be best to get from your Arista support team, as any other config/services you have defined would need to be considered.</div><div style="color: rgb(0, 0, 0);"><span><br /></span></div><div>The other, less technical way, is to use fanout ports. This means you burn a port for the uplink and then two ports for each member delivered via that uplink.
