39NOTE:• Route related attributes configured in VPN instance view are applicable to both IPv4 VPNs and IPv6VPNs.• You can configure route related attributes for IPv6 VPNs in both VPN instance view and IPv6 VPN view.Those configured in IPv6 VPN view take precedence.Configuring routing on an IPv6 MCEAn IPv6 MCE implements service isolation through route isolation. IPv6 MCE routing configurationincludes:• IPv6 MCE-VPN site routing configuration• IPv6 MCE-PE routing configurationOn the PE in an IPv6 MCE network environment, disable routing loop detection to avoid route loss duringroute calculation and disable route redistribution between routing protocols to save system resources.IPv6 static routing, RIPng, OSPFv3, IPv6 IS-IS, or EBGP can be used between an IPv6 MCE and a VPNsite or a PE.Configuration prerequisitesBefore you configure routing on an IPv6 MCE, complete the following tasks:• On the IPv6 MCE, configure VPN instances, and bind the VPN instances with the interfacesconnected to the VPN sites and those connected to the PE.• Configure the link layer and network layer protocols on related interfaces to ensure IP connectivity.Configuring routing between IPv6 MCE and VPN siteConfiguring static routing between IPv6 MCE and VPN siteAn IPv6 MCE can reach a VPN site through an IPv6 static route. IPv6 static routing on a traditional CEis globally effective and thus does not support address overlapping among VPNs. An IPv6 MCE supportsbinding an IPv6 static route with an IPv6 VPN instance, so that the IPv6 static routes of different IPv6 VPNinstances can be isolated from each other.To configure IPv6 static routing between IPv6 MCE and VPN site:Step Command Remarks1. Enter system view. system-view N/A
