Configuring FRR for IPv6 Routes on a Private Network

Configuring FRR for IPv6 Routes on a Private Network

You can configure IPv6 FRR for a private network where multiple CEs at an IPv6 VPN site access the same PE. This feature can quickly switch traffic to a link connected to another CE if the primary link from the PE to a CE becomes unreachable.

Pre-configuration Tasks

Before configuring FRR for IPv6 routes on a private network, complete the following tasks:

Context

This feature is suitable for IP services that are sensitive to the packet loss and delay on a VPN. With IPv6 FRR configured on the private network, if the route from a PE to a CE is unreachable, traffic from the PE can be quickly switched to a link connected to another CE. This ensures non-stop forwarding of IP services.

The switch supports two methods of implementing IPv6 FRR for the private network. Each method applies to a different networking environment and is configured differently.

  • IPv6 FRR: used when different routing protocols are running between PE and CE devices.

  • BGP auto FRR: used when only BGP is running between PE and CE devices.

Procedure

  • Configuring IPv6 FRR
    1. Run system-view

      The system view is displayed.

    2. Run ip vpn-instance vpn-instance-name

      The VPN instance view is displayed.

    3. Run ipv6-family

      The VPN instance IPv6 address family view is displayed.

    4. Run ipv6 frr

      IPv6 FRR is enabled.

    5. Run commit

      The configuration is committed.

  • Configuring BGP auto FRR for the private network
    1. Run system-view

      The system view is displayed.

    2. Run bgp { as-number-plain | as-number-dot }

      The BGP view is displayed.

    3. Run ipv6-family vpn-instance vpn-instance-name

      The BGP-VPN instance IPv6 address family view is displayed.

    4. Run auto-frr

      BGP auto FRR is enabled.

    5. (Optional) Run route-select delay delay-value

      A delay for selecting a route to the intermediate device on the primary path is configured. After the primary path recovers, an appropriate delay ensures that traffic switches back to the primary path after the intermediate device refreshes forwarding entries.

      The default value of delay-value is 0, indicating that the device on which FRR is configured selects a route to the intermediate device on the primary path without a delay.

    6. Run commit

      The configuration is committed.

Verifying the Configuration

Run the display ipv6 routing-table vpn-instance vpn-instance-name [ ipv6-address ] verbose command to check the backup outbound interface and backup next hop of the IPv6 route in the routing table.
