Hi Asish,
Egress LER is the one that is on the edge of the MPLS domain. On the egress interface of this LER there is no MPLS encapsulation. (See RFC3031)

Other LSRs can pop label eg in case of BGP/MPLS based VPNs (RFC2547).

Subject: Doubt about Egress Label Edge Router

Hi all,

LSRs along the LSP swap the label on the top of the label stack and forward
the packet and Egress LER pops the label and then forwards the packed. can
any other LSR pop out the label? What is the Definition of Egress LER? If an
LSR who can POP the label, is a Egress router?

Thanks In Advance
