18 global-merge-capability, Global, Merge – PLANET XGS3-24042 User Manual
Page 1192: Capability

76-10
Command Mode:
Interface Mode.
Usage Guide:
The LDP protocol is a label switching protocol used when switching labels in the public network,
which usually works in a BGP VPN environment. “router ldp” is used to globally enable the LDP
protocol, however, in interfaces where the protocol is actually working, implementing “ldp enable” in
the interface configuration mode is required, so does enabling Label-switching, which, in
combination with this command, work as a whole to ensure the normal operation of the protocol.
Example:
Switch(config)#int vlan 9
Switch(Config-if-Vlan9)#ldp enable
Related Commands:
router ldp, label-Switching
76.18 global-merge-capability
Command:
global-merge-capability {merge-capable|non-merge-capable }
no global-merge-capability {merge-capable|non-merge-capable }
Function:
Enable or disable globally the LDP label merging capability; the no operation will restore the default
value.
Default:
Enable the label merging capability globally.
Command Mode:
LDP Protocol Configuration Mode.
Usage Guide:
The LSP map multiple in-labels to the same FEC, corresponding with the same out-label and
out-interface, in which case, when packets with different labels enter the LSR, the output packets
will bear the same label. This procedure is called label merging. If the label-merging capability on
the interface changes, the switch will reboot.
Example:
Switch(config)#router ldp
Switch(config-router)#global-merge-capability non-merge-capable
