so in my example:
Core <bgp> Tower1 (tower 1 is a main distribution point to other towers)
Tower1 <bgp> Tower2
Tower1 <bgp> Tower3
Tower1 <bgp> Tower4
I can extend this to say
Tower2 connects to Tower 3, which makes Towers 1,2,3 in a triangle shape.
Tower3 connects to Tower 4, making 1,3,4 a triangle shape.
This means a ton for static routes.
Also, if I have a subnet at the end of this topology Core>Tower1>Tower4>Tower5>CPE, each tower has it's own subnet which means 4 networks, I have 4 static routes to add
ibgp means 0 static routes.
I was thinking I would use ibgp for this for simplicity, but without route filters I am getting huge route lists and loops etc etc.
Maybe I should be looking at OSPF instead?
