In this event we will answer all your questions related to dynamic routing protocols with IPv6 configuration, verification, troubleshooting, and general best current practices. All questions regarding design, in-depth mechanics, and features of the Routing Information Protocol for IPv6, OSPFv3, ISIS, EIGRPv6, and BGP are welcome.

6PE and 6VPE allow us to run IPv6 over an IPv4-only MPLS core where we use dual stack PE routers.
This allows service providers to offer IPv6 to their customers without making major changes to the core of their MPLS network.
The main difference between 6PE and 6VPE will be:

Both 6PE and 6VPE transport IPv6 traffic over the MPLS core. The MPLS core does not need to be running IPv6 at all (except for the PE). IPv6 traffic will be encapsulated in an MPLS LSP and forwarded to the relevant egress PE.
The difference between the two is that 6PE works using the global routing table on the PE, whereas 6VPE will perform the IPv6 lookup from a VRF routing table on the PE. So 6VPE is equivalent to IPv4 L3VPN.
Much of OSPF version 3 is the same as in OSPF version 2. OSPFv3, which is described in RFC 5340, expands on OSPF version 2 to provide support for IPv6 routing prefixes and the larger size of IPv6 addresses.
Here are the OSPFv3 LSA types.
The following list describes LSA types, each of which has a different purpose:
IPv6 RIP works the same and offers the same benefits as RIP in IPv4. RIP enhancements for IPv6, detailed in RFC 2080, include support for IPv6 addresses and prefixes, and the use of the all-RIP-devices multicast group address FF02::9 as the destination address.
- Make sure Ipv6 unicast-routing is enabled.
- Configure IPv6 RIP on the interface.
Here is the configuration guide for more information.
