You need a "router" to append something to the as-path in order to do
loop avoidance...

One could configure an LR for this purpose. Add a logical tunnel
interface pair between the main guy and the LR and loop routes that
way, via peering through the LR.

I haven't tried this myself so i don't have configs but it should be
doable.

Still, back to hub and spoke, do you really need to reflect spoke
routs back to other spokes ? shouldn't you be able to aggregate them
and/or inject a default at the hub ?

  Pedro.
