Technical Summary A mechanism for BGP that would help minimize the negative effects on routing caused by BGP restart is described in "Graceful Restart Mechanism for BGP". This document extends this mechanism to also minimize the negative effects on MPLS forwarding caused by the Label Switching Router's (LSR's) control plane restart, and specifically by the restart of its BGP component when BGP is used to carry MPLS labels and the LSR is capable of preserving the MPLS forwarding state across the restart. Working Group Summary The WG had consensus to progress this document. Protocol Quality The specification has been reviewed for the IESG by Alex Zinin. There are at least two known implementations.
