RE: MPLS Aggregate label

Found another good and quick description in the MPLS Architecture book:

Action Description
Aggregate Removes the top label in the stack and performs a Layer 3
lookup.
Pop Removes the top label in the stack and transmits the
remaining payload as either a labeled packet or unlabeled IP packet.
Push Replaces the top label in the stack with a set of labels.
Swap Replaces the top label in the stack with another value.
Untag Removes the top label and forwards the IP packet to the
specified IP next hop.

regards

Roger
