About MPLS label range

fr flag

In most routers or switches that support MPLS, if transit label and uhp LSP label need to have a different label range? when protocol(LDP or BGP) assign labels, I know that VPN label and LSP tunnel label have different range, but I'm not very clear if transit label and termination LSP label have different label range?

An MPLS label is a 20-bit field, so the range is 0 to 1048575. There is no set definition for values for a specific purpose, so every manufacturer does it differently. Cisco, among others, allows you to modify the label ranges to suit your needs.

Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
