How To Implement 6Pe/Vpe; Configuring 6Pe/Vpe - Cisco CRS Configuration Manual

Implementing IPv6 VPN Provider Edge Transport over MPLS
• DN bit processing—In VRF lite environment, the DN bit processing is disabled.
• ABR status—In VRF context (except default VRF), OSPFv3 router is automatically set as an ABR,
To enable VRF Lite, issue the capability vrf-lite command in the OSPFv3 VRF configuration submode.

Configuring 6PE/VPE

This task describes how to configure 6PE/VPE on PE routers to transport the IPv6 prefixes across the IPv4
cloud.
Ensure that you configure 6PE/VPE on PE routers participating in both the IPv4 cloud and IPv6 clouds.
Note To learn routes from both clouds, you can use all routing protocols supported on Cisco IOS XR software:
BGP, OSPF, IS-IS, EIGRP, RIP, and Static.
SUMMARY STEPS
1. configure
2. router bgp as-number
3. neighbor ip-address
4. remote-as as-number
5. address-family ipv6 labeled-unicast
6. exit
7. exit
8. address-family ipv6 unicast
9. allocate-label [all | route-policy policy_name]
10. Use the commit or end command.
DETAILED STEPS
Step 1
configure
regardless to it's connectivity to area 0. This automatic ABR status setting is disabled in the VRF lite
environment.
