fec 
fec prefi xfec vc-type
Syntax fec prefix [ip-prefix/mask]
fec vc-type {ethernet|vlan} vc-id vc-id
Context tools>dump>router>ldp 
Description This command displays information for an LDP FEC.
Default none
Parameters ip-prefix/mask — Specifies the IP prefix and host bits. 
Values host bits:    must be 0
mask: 0 — 32
vc-type — Specifies the VC type signaled for the spoke or mesh binding to the far end of an SDP. 
The VC type is a 15 bit-quantity containing a value which represents the type of VC. The actual 
signaling of the VC type depends on the signaling parameter defined for the SDP.  If signaling is 
disabled, the vc-type command can still be used to define the dot1q value expected by the far-end 
provider equipment. A change of the binding’s VC type causes the binding to signal the new VC 
type to the far end when signaling is enabled. 
VC types are derived according to IETF draft-martini-l2circuit-trans-mpls. 
• Ethernet — The VC type value for Ethernet is 0x0005. 
• VLAN — The VC type value for an Ethernet VLAN is 0x0004.
vc-id — Specifies the virtual circuit identifier.
