Configuring VPN GR

Configuring VPN GR

Context

In GR process, two roles are defined according to their functions, that is, GR restarter and GR helper.
  • GR restarter: performs active/standby control board switchover or the system upgrade.
  • GR helper: helps the GR restarter to implement uninterrupted service forwarding.

VPN GR is the collection of GR capabilities of various protocols running on devices on VPN networks. You need to configure IGP GR, BGP GR, MPLS LDP GR, or MPLS TE GR based on the related protocol running on the GR restarter. You also need to configure neighboring devices of the GR restarter as the GR helper to help the GR restarter implement uninterrupted service forwarding. A device can function as the GR restarter or the GR helper.

Configure specified VPN GR on the PE, CE, and P as follows:
  • Configure IGP GR, BGP GR and MPLS LDP (or MPLS TE) GR on the PE device.
  • Configure IGP GR and the MPLS LDP (or MPLS TE) GR on the P device.
  • Configure IGP GR or the BGP GR on the CE device.
  • If a VPN spans multiple ASs, you must configure the IGP GR, BGP GR and MPLS LDP GR on the ASBR.
NOTE:

The GR capability cannot ensure uninterrupted traffic forwarding when the neighboring device performs an active/standby switchover at the same time.

Pre-configuration Tasks

Before configuring VPN GR, complete the following tasks:

Procedure

  • Configure IS-IS GR or OSPF GR.

    • For details about how to configure IS-IS GR, see Enabling IS-IS GR in "IPv4 IS-IS Configuration" in the S9300, S9300E, and S9300X V200R010C00 Configuration Guide - IP Unicast Routing.
    • For details about how to configure OSPF GR, see Configuring OSPF GR in "OSPF Configuration" in the S9300, S9300E, and S9300X V200R010C00 Configuration Guide - IP Unicast Routing.

  • Configure BGP GR.

    • For details about how to configure BGP GR, see Configuring BGP GR in "BGP Configuration" in the S9300, S9300E, and S9300X V200R010C00 Configuration Guide - IP Unicast Routing.

  • Configure MPLS LDP GR or MPLS TE GR.

    • For details about how to configure MPLS LDP GR, see Configuring LDP GR in "MPLS LDP Configuration" in the S9300, S9300E, and S9300X V200R010C00 Configuration Guide - MPLS.
    • For details about how to configure MPLS TE GR, see Configuring RSVP GR in "MPLS TE Configuration" in the S9300, S9300E, and S9300X V200R010C00 Configuration Guide - MPLS.
