Which of the routers is the iLER for LSP B?
The iLER (Ingress Label Edge Router) for LSP B is the router where the LSP (Label Switched Path) begins. In this case, LSP B starts at Router R1, making it the iLER. Therefore, Router R1 is the correct answer.
assuming that LSP B goes from R4 to R1, and refer to study guide: "The first PE router is called the Ingress Label Edge Router (iLER)" "The last PE router on the LSP is the Egress Label Edge Router (eLER)" the correct answer is D (R4 is iLER for LSP B)
answer should be D
