Abstract
Techniques are described for routing data frames using a distributed virtual bridge in a highly integrated networked system. The distributed virtual bridge creates and manages a type of LAG referred to as 'unified link aggregation group' (ULAG). Two or more link aggregation groups that span multiple physically-separated switches or chassis (referred to as MLAGs) are unified or aggregated to form a ULAG. Applications view the ULAG as a single logical link, and as long as at least one of the sub links in any of the MLAGs that are part of the ULAG is operational, network connectivity is maintained.
