Routing

Greetings.

I have been struggling with completing a setup in the lab where I have 2 MX's routers acting as PEs.  The default RI is configured for MPBGP peering where both IPv4 and IPv6 routes will be distributed to various VRFs. The Ipv4 works fine.  I have gone through many different websites and tried many configurations and I am still unable to get the IPv6 routes to become usable.  I know I am missing a secret sauce but at this point I am unable to figure it out.  Looking for valid suggections (really appreciate it).

I am using the Mapped IPv4<>IPv6 addresses for the interfaces between the 2 nodes.  The route I am concerend with is 2021:........ 

The interface ae44 is the link from the MX to a series of QFX switched where the end CE device is located.  VLAN 2300 and 2301 are the redundant paths to the end device, I cna ping both the IPv4 and v6 addresses across the links.  I am only working on 1 of the PEs at the moment to get the setup working.  IPv4 is working to both PEs today.

Please let me know what other info you need to look at.  Again, I really appreciate the help in advance.

Hello,

There is a lot of configuration that is extra or not needed. There's a confusion in your rib-groups, you have a lot of tables in "myrib" and you're not applying it anywhere, so it's not doing anything. Also, you are making routes from bgp.l3vpn.0 to be resolved via inet.0, which makes me think you have no routes in inet.3, so no routes will be copied to inet6.3 with "ipv6-tunneling". Could you share a simple diagram with the devices, connections and IP's (phy interfaces, sub-interfaces/vlans and loopbacks). (This could speed up if I could access the lab via teamviewer or something similar)

This could show you a bit what is happening:

show route resolution unresolved         

show route receive-protocol bgp 10.229.21.1 table bgp.l3vpn-inet6.0 hidden  <<< Get the next hop x.x.x.x

show route x.x.x.x

You are corect, there are no routes in inet.3 or inet6.3.  Some of this configuration I used from a few websites showing IPv4.  All the routes and traffic flow are correct and work (by accident, maybe) for v4 but the issue is v6 and some of that very well can be a misunderstanding. 

MPBGP is new to me and the work I am doing.  I will try to put a pic together.

Don't worry, 6PE and 6VPE is and advanced topic if you're new to MP-BGP.

Your issue is that ::ffff:10.229.21.1 is not present on inet6.3, and bgp.l3vpn-inet6.0 resolves it's routes next-hops with inet6.3. I understand the PE's are directly connected (no need for an LSP to reach 10.229.21.1), so you can use a rib-group to export the direct route 10.229.21.1 from inet.0 to inet6.3, this will automatically place the route as an ipv6 ipv4-mapped address in inet6.3. The simplest way to do this:

set routing-options rib-group inet0-inet63 import-rib [inet.0 inet6.3]          <<< create the rib-group stating that routes placed in inet.0 should also be placed in inet6.3 (this does not do anything by itself)

set routing-options interface-routes rib-group inet inet0-inet63        <<< this applies the rib-group to the interface routes (protocol direct) in the router.

You could also add a policy to filter only 10.229.21.1/32 in the rib-group.

Kindly try that and check again the same commands.

I want to thank you for your time.  I had to modify the command you provided as if gave an error (inet.0 vs inet6.0) .  The biggest thing is learning how all the various route tables are used and shared with the system. 

set routing-options rib-groups inet0-inet63 import-rib inet6.0
set routing-options rib-groups inet0-inet63 import-rib inet6.3

set routing-options interface-routes rib-group inet6 inet0-inet63

set routing-options rib inet6.3 static route ::ffff:10.229.21.1/128 next-hop ::ffff:10.220.21.2
set routing-options rib inet6.3 static route ::ffff:10.229.21.1/128 next-hop ::ffff:10.220.21.6

I was able to ping from the PE to a loopback on the end device and it works. 

Hi,

What is your traceroute output from CE to CE as the go through the 6VPE infra? Are the MPLS label and the ipv4-to-ipv6mapped Next-hop are shown in the traceroute?

thanks
