Resource summary

Question 1

Question
SD-Wan configuracion setting needed:
Answer
  • Member interfaces Load balancing method
  • Group member interfaces Load balancing algorithm

Question 2

Question
[blank_start]Source IP[blank_end]: Traffic from the same IP address uses the same link. [blank_start]Source-destination IP[blank_end]: Traffic from the same pair of source and destination IP addresses uses the same link. [blank_start]Spillover[blank_end]: This method is similar to the spillover method used by ECMP. A link routes all the traffic until the volume reaches a threshold, after that, another link is used. [blank_start]Sessions[blank_end]: The interface weights determine the proportion of sessions that each link should handle. Sessions are distributed among the links, based on the interface weights. [blank_start]Volume[blank_end]: The interface weights determine the proportion of traffic volume that each link should handle. Sessions are balanced so that traffic volume is distributed based on the interface weights.
Answer
  • Source IP
  • Source-destination IP
  • Spillover
  • Sessions
  • Volume
