Hello friends, once again I'm stuck somewhere in networking where I can't quite wrap my head around something. Really sorry about the poor drawing by the way.
Let's say I have a small topolgy of 3 routers attached in a triangle below.
ISP |eBGP | RT1 eBGP/ \ ospf / \ RT2 ----- RT3. ospf RT1 is learning only a default route from the ISP via eBGP.
RT2 somehow knows this default Route from BGP peering to RT1. Is this automatic? Will one eBGP neighbor always relay its default to another eBGP neighbor or do I need to explicitly redistribute this or network it to the other neighbor?
