Fill in the blanks: The device at the beginning of an LSP is referred to as the_________, and the device at the end of an LSP is referred to as the ___________.
An LSP (Label Switched Path) in MPLS (Multiprotocol Label Switching) technology starts from an ingress Label Edge Router (iLER) and ends at an egress Label Edge Router (eLER). The iLER is the device at the beginning of the LSP, and the eLER is the device at the end of the LSP.
I think it should be D,E
No, LSP always goes from iLER to eLER, so only D is correct.
