[j-nsp] Collapsed MPLS CE/PE/P configuration

[Matthew Crocker]

Hello,

 I have 3 MX series routers connected via 3 10G circuits  A - B - C -A.   
 OSPD, MPLS, RSVP, LDP are all running
 inet-vpn any configured on the BGP groups

 I’m trying to build a routing-instance on MX-A & MX -B with some local interfaces and then have the two routing-instances be able to talk to each other over the MPLS network (A-B or A-C-B)

 Does anyone have any documentation on how to configure this?  I’ve read a bunch of L3VPN JunOS docs but they all have CE, PE, P routers.   In my case the routers A & B are acting as CE & PE while router C is acting as P

MX-A has a config:

CROCKER-VOIP {
    instance-type vrf;
    interface ge-2/0/8.13;
    route-distinguisher 10.126.13.1:1;
    vrf-export export-direct;
    vrf-target target:7849:13;
}

# run show route table CROCKER-VOIP 

CROCKER-VOIP.inet.0: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

10.126.13.0/30     *[Direct/0] 00:38:46
                    > via ge-2/0/8.13
10.126.13.1/32     *[Local/0] 00:38:46
                      Local via ge-2/0/8.13

MX-B has a config:

routing-instance
CROCKER-VOIP {
    instance-type vrf;
    interface ae0.301;
    interface ae0.302;
    route-distinguisher 10.127.13.1:1;
    vrf-export export-direct;
    vrf-target target:7849:13;
}

# run show route table CROCKER-VOIP 

CROCKER-VOIP.inet.0: 4 destinations, 4 routes (4 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

10.127.13.0/30     *[Direct/0] 00:47:21
                    > via ae0.301
10.127.13.1/32     *[Local/0] 00:47:21
                      Local via ae0.301
10.127.13.4/30     *[Direct/0] 00:47:21
                    > via ae0.302
10.127.13.5/32     *[Local/0] 00:47:21
                      Local via e0.302


A ‘show run bgp sum’    bgp.l3vpn.0  with 0 routes


Do I need to build a MPLS connection interface between the two routing-instances?
