Graceful Restart Mechanism for BGP
نویسندگان
چکیده
This document describes a mechanism for BGP that would help minimize the negative effects on routing caused by BGP restart. An End-of-RIB marker is specified and can be used to convey routing convergence information. A new BGP capability, termed "Graceful Restart Capability", is defined that would allow a BGP speaker to express its ability to preserve forwarding state during BGP restart. Finally, procedures are outlined for temporarily retaining routing information across a TCP session termination/re-establishment.

RFC 4781 Graceful Restart Mechanism for BGP
A mechanism for BGP that helps minimize the negative effects on routing caused by BGP restart has already been developed and is described in a separate document ("Graceful Restart Mechanism for BGP"). This document extends this mechanism to 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 it...
متن کاملGraceful Restart Mechanism for Label Distribution Protocol
This document describes a mechanism that helps to minimize the negative effects on MPLS traffic caused by Label Switching Router’s (LSR’s) control plane restart, specifically by the restart of its Label Distribution Protocol (LDP) component, on LSRs that are capable of preserving the MPLS forwarding component across the restart. The mechanism described in this document is applicable to all LSRs...
متن کاملRFC 6198 Reqs for Graceful BGP
The Border Gateway Protocol (BGP) is heavily used in Service Provider networks for both Internet and BGP/MPLS VPN services. For resiliency purposes, redundant routers and BGP sessions can be deployed to reduce the consequences of an Autonomous System Border Router (ASBR) or BGP session breakdown on customers’ or peers’ traffic. However, simply taking down or even bringing up a BGP session for m...

متن کاملExtensions to GMPLS Resource Reservation Protocol (RSVP) Graceful Restart
The extensions defined in this document build on the RSVP Hello extensions defined in RFC 3209, and extensions for state recovery on nodal faults defined in RFC 3473. Using these extensions, the restarting node can recover all previously transmitted Path state, including the Explicit Route Object and the downstream (outgoing) interface identifiers. The extensions can also be used to recover sig...
