Application environment
In MPLS network, L3VPN application needs to configure L3VPN GR on the service-carrying
device, so that this device can ensure non-stop data forwarding during main-slave management
board switchover, and the service traffic can maintain uninterrupted.
Note
When the neighboring devices experience main-slave management board
switchover at the same time, GR capability cannot guarantee non-stop
traffic.
Prerequisites
Before configuring L3VPN GR, the following configuration tasks must be completed:
¾ Build L3VPN environment and configure L3VPN.
¾ Support management board redundancy.
¾ Make sure IGP protocol is GR-Capable.
¾ Make sure BGP protocol is GR-Capable.
¾ Make sure LDP protocol is GR-Capable.
Data preparation
Before configuring L3VPN GR, the following data must be prepared:
¾ IGP GR parameters.
¾ BGP GR parameters.
¾ LDP GR parameters.
Configure L3VPN
Note
To configure L3VPN GR, you must configure L3VPN first. Please refer to
"BGP/MPLS VPN Configuration" for L3VPN configuration.
