When the ingress LER signals the path of an auto-created mesh LSP, it includes the name of the LSP and the path name in the Session Name field of the Session Attribute object in the PATH message. The encoding is as follows:
Session Name: <lsp-name::path-name>, where the lsp-name component is encoded as follows:
TemplateName-DestIpv4Address-TunnelId
where DestIpv4Address is the address of the destination of the auto-created LSP.
