 * to a variety of groups in a group chain, depending on the whether
 * MPLS labels are being pushed or not.

 * NOTE: We do not create MPLS ECMP groups as they are unimplemented in
 *       OF-DPA 2.0 (even though it is in the spec). Therefore we do not
 *       check the nextObjective meta to see what is matching before being

Example 25 with GroupId

use of org.onosproject.core.GroupId in project onos by opennetworkinglab.

the class SimpleVirtualGroupStore method storeGroupDescriptionInternal.
