Configure SPBM IPv6 Layer 3 VSN using CLI

Before you begin

  • You must enable IPv6 Shortcuts.

  • You must configure the required SPBM IS-IS infrastructure.

  • You must configure a VRF instance on the switch. For more information, see VRF Lite configuration using the CLI.

About this task

After you have configured the SPBM infrastructure, you can enable SPBM Layer 3 VSN to advertise IPv6 routes across the SPBM network using the following procedure.

Procedure

  1. Enter VRF Router Configuration mode for a specific VRF context:

    enable

    configure terminal

    router vrf WORD<1-16>

  2. Create an IPv6 VPN instance on the VRF:

    ipv6 ipvpn

  3. Configure SPBM Layer 3 VSN:

    i-sid <0–16777215>

  4. Enable IPv6 VPN on the VRF:

    ipv6 ipvpn enable

  5. Display all IPv6 VPNs:

    show ipv6 ipvpn [vrf WORD<1–16> | vrfids WORD<0–512>]

  6. Identify routes on the local switch to be announced into the SPBM network:

    ipv6 isis redistribute {bgp | direct | ospf | static}

  7. Enable routes on the local switch to be announced into the SPBM network:

    ipv6 isis redistribute {direct | bgp | ospf | rip | static} enable

  8. Identify the routing protocol to which to redistribute IS-IS routes:

    ipv6 ospf redistribute isis

  9. Enable IS-IS redistribution to OSPF:

    ipv6 ospf redistribute isis enable

  10. Return to Privileged EXEC mode:

    end

  11. Apply the configured redistribution to a specific VRF:

    ipv6 isis apply redistribute {direct | bgp | ospf | rip | static} vrf WORD<1–16>

  12. Apply the OSPF configuration to a specific VRF:

    ipv6 ospf apply redistribute isis vrf WORD<1-16>

  13. Display the redistribution configuration:

    show ipv6 isis redistribute [vrf WORD<1–16> | vrfids WORD<0–512>]

  14. Verify IPv6 IS-IS routes:

    show ipv6 route vrf WORD<1-16>

Examples

Create the IPv6 VPN instance:

Switch:1(router-vrf)#ipv6 ipvpn
