I am testing the L3HW of CCR2216, which I plan to put into production next week, by injecting routes using BGP replay tool.
I found these two cases, where both are not in the 60k-120k range mentioned in
https://help.mikrotik.com/docs/display/ ... Offloading:
1. 37k out of 50k prefixes are in L3HW
2. 300k out of 300k prefixes are in L3HW
My questions are:
1. Does CCR2216 do dynamic updates of route prefixes in L3HW based on the traffic?
2. Any effective route filter techniques to maximize prefixes in L3HW?
Thanks
