label advertise
 { explicit-null | 
implicit-null
 | non-null } 
Optional 
By default, an egress supports 
PHP and distributes to the 
penultimate hop an implicit null 
label. 
Note that you must reset LDP 
sessions for the configuration 
to take effect. 
 
 
For the S7900 series Ethernet switches, a label with a value of 0 can be at the top of a label stack. After 
receiving a packet with such a label, the switch will pop the label directly and check whether there is any 
inner layer label. If finding an inner layer label, the switch will forward the packet based on the inner 
layer label; otherwise, the switch will forward the packet based on the IP address. 
 
Configuring a Static LSP 
An LSP can be static or dynamic. A static LSP is manually configured, while a dynamic LSP is 
established by MPLS LDP. 
For a static LSP to work, all LSRs along the LSP must be configured properly. 
Static LSPs can be used in MPLS L2VPN. 
 
 
For configuration of MPLS L2VPN, refer to MPLS L2VPN Configuration in the MPLS Volume
