Yeah I was all about L3 everywhere.  I changed my tune when it was time to bring 400+ mbps to even very small sites.  I looked at the routers I would use for 400mbps+ and their size and power consumption and I'm trying to fit that into a little battery backed cabinet mounted on a pole.  Then compare to a switch that carries the same traffic and you look at your capital savings, your space savings, your power consumption savings, your increased battery runtime, your lower heat output, and it became obvious that I was thinking wrongly.

Routers do keep getting faster, but a switch generally runs wire speed to every port without touching the CPU.

We learned the hard way just like everyone else, but got the wrong lesson and put in big routers everywhere.  Too expensive to upgrade to 10G and way too much power usage which requires big expensive batteries.  Now we are moving to ERPS rings on Calix with a few BNGs, a couple DIA customer edge routers, and two peering routers.

L2 network --> Routed Network --> L2 payload network via MPLS VPLS over the routed network --> L2 network

If I had understood how a BNG can dynamically create individual interfaces per sub and use one big IP pool with IPoE in the beginning, I think we would be a lot further along then we are now.

    Cheap managed switch, VLANs, every AP on a router via VLAN etc. 
    Unless routers are as cheap as switches these days that is how I
    would still be building things.

    I’ve got towers with a router for all the backhauls and a managed
    switch for the APs.  And I’ve got 1 or 2 towers with 2 routers,
    one for all the ins and outs, and another for the APs at that
    tower.  I don’t connected backhauls to switches.  Although a
    switch with VLANs connected to a router really blurs the lines
    since the router can route at L3 to the VLANs and hence to ports
    on the switch.

    Something like a Mikrotik CCR1009 or CCR1036 has the ports
    connected directly to the CPU.  And even something like an
    RB1100AHx4 may have a couple switch chips between the CPU and the
    Ethernet ports but other than a 2.5 Gbps bottleneck per switch
    chip they are still routed ports (or can be).

    I think it’s more a question of separate hardware for lightning
    protection, POE, switch and router, or combine some or all of them
    into one box.  Less wires, more to replace if it fails or gets
    zapped.  Probably also matters if you are putting it on the ground
    or up in the air.

    The 'routers' that most WISP's use are really more like a L3
    switch than a router....   They usually have a switch chipset
    glued onto a CPU.

            connecting everything to the router doesn't scale.
