If packets have a single label, that label is usually a global address or terminal VPN label. Those packets
can be forwarded through the use of the global IP routing table. Packets that have more than one label
can be forwarded through the use of the original label stack. Enter the mpls ip ttl-expiration pop 1
command to enable forwarding based on more than one label. (This is the most common application of
the command.)
Examples The following example shows how to enable forwarding based on more than one label:
Router(config)# mpls ip ttl-expiration pop 1
