We have Juniper 14x EX4200 as access switches, and 2x EX8208 with virtual chassis configured between the 2 EX8208.
from the access switched EX4200 we need 2 links.. one for the core A and second for core B since the core switches are considered as one switch (virtual chassis) what is the best practice here, can i use LACP link aggregation on the core switch and access switches? or do i need to use RTG Redundant Trunk Groups
Note: im using 10G fiber interfaces
Thanks.
