Please see attached screenshot. This is of a router, say R2, which is sandwiched between 2 other MT routers , R1 & R3 directly connected to interfaces ether_1, and ether_6 on R2
ISP1 <- >R1< - > R2 < - >R3< - >ISP2.
Ospf is running across all 3 routers, R1, 2 & 3. BGP is running on R1 and R3 only.
What seems to be happening to R2 is that its preferred gateway is ether_6, which ip/routes correctly indicates. but traffic is almost symmetrical, which it should not be. It also seem to be receiving traffic from ether_1, which I have weighted higher to stop R2 from using this interface unless ether_6 goes down.
How would I go about diagnosing this problem?
