We operate a small WISP environment where each tower/bldg. rooftop utilizes a CCR1036. Some towers have fiber PtP towards to the core, and the towers without fiber access utilize mmWave PtPs to the nearest fiber lit buildings as the next hop. I am running eBGP towards the core and between all the tower peerings. The CCRs that peer with the core (Juniper QFX5100) receive a default route and I am trying to understand if the CCR1036s forward the def route to other towers only if "default originate / if installed" is enabled.
I attached a diagram that illustrates this a little more. Would I need to enable default originate on all the CCRs to accomplish the following? Can the CCRs just forward the def. and then I can manipulate the paths via local pref/weight? I don't see how this will work if for example Towers 3 & 4 originate def. routes to each other.
-primary path through Tower2
-secondary path through Tower4 and 5
-primary path through Tower5
-secondary path through Tower3 and 2
