The following interface modules support PHP only when the operating mode is bridging or
normal:
EA interface modules:
−
−
−
−
EB interface modules:
−
−
−
SE interface modules:
−

For more information about the operating modes, see Fundamentals Configuration Guide.
•
If the switch acts as an egress, it can de-encapsulate MPLS packets with a maximum of two
labels.
•
SC interface modules do not support MPLS:
•
Basic MPLS is mutually exclusive with EVI and VXLAN. For more information about EVI and
VXLAN, see EVI Configuration Guide and VXLAN Configuration Guide.

Enabling MPLS
Before you enable MPLS, perform the following tasks:
•
Configure link layer protocols to ensure connectivity at the link layer.
•
Configure IP addresses for interfaces to ensure IP connectivity between neighboring nodes.
•
Configure static routes or an IGP protocol to ensure IP connectivity among LSRs.
