Outbound BGP traffic oscillation.
Blue line is ISP.
Tortoise line is Megaport IXP.
Pink line is the sum of both.
After adding rule:
add action=passthrough chain="In_Filter_Megaport IX" comment="Set LOCAL PREF to 200 to favor the IXP routes over ISP" set-bgp-local-pref=200*
Has helped by about 15Mbps however still seeing the 15Mbps oscillation. This is likely caused by rout changes. Now to determine which ones.
The black bar is when I added the above rule.
