Abstract
A mixed Multiprotocol Label Switching (MPLS) network includes both extension header capable (EH capable) nodes and EH non-capable nodes. A first EH capable node receives advertised capabilities of a downstream node. These advertised capabilities indicate whether the downstream node is EH capable. The first EH capable node receives a packet to be transmitted to the downstream node via the MPLS network, and determines whether the packet includes an extension header (EH). The node inserts an EH label into an MPLS label stack of the packet after determining the advertised capabilities of the downstream node indicate that the downstream node is EH capable, and after determining the packet does not include the EH.
