Routing

Question 1

What are the four ECMP load balancing algorithms

Answer 1

Source IP (default)
Source-destination IP
Weighted
Usage (spillover)

Question 2

What does the ECMP Source IP load balancing algorithm do?

Answer 2

Sessions source from the same address use the same route.

Question 3

What does the ECMP Source-destination IP load balancing algorithm do?

Answer 3

Sessions with the same source and destination address take the same route.

Question 4

What does the ECMP weighted load balancing algorithm do?

Answer 4

Used for static routes.
FTG load balances based on the route or respective interface weight. The higher the weight the higher the number of sessions.

Question 5

What does the Usage ECMP load balancing algorithm do?

Answer 5

Fill up the first link then spillover to the next.

Question 6

Do SD-WAN rules have precedence over policy routes?

Answer 6

No, they just have precedence over FIB entries.

Question 7

True or false: does FTG hide v4-ecmp-mode when you turn on SD-WAN?

Answer 7

Yes, it replaces it with load-balance-mode.

Question 8

What ECMP load balancing algorithm does load-balance mode support that v4-ecmp-does not?

Answer 8

volume mode
