Egress router
open-in-new
<p>An egress router is a <a href="/facts/Label_switch_router/k7cx1PWw">label switch router</a> that is an end point (drain) for a given <a href="/facts/Label-switched_path/k7cx1PWw">label-switched path</a> (LSP). An egress router may be an <a href="/facts/Ingress_router/n5Maxveh">ingress router</a> or an intermediate router for any other LSP(s). Hence the role of egress and ingress routers is LSP specific. Usually, the <a href="/facts/Multiprotocol_Label_Switching/k7cx1PWw">MPLS</a> label is attached with an IP packet at the ingress router and removed at the egress router, whereas label swapping is performed on the intermediate routers. </p>
