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

[Aaron]

Maybe this will help...

this makes L3VPN work for me on a PE...

set interfaces ge-0/0/47 mtu 9192
set interfaces ge-0/0/47 unit 0 family inet address 10.101.14.118/30
set interfaces ge-0/0/47 unit 0 family mpls
set interfaces lo0 unit 0 family inet address 10.101.12.245/32
set interfaces lo0 unit 1 family inet address 1.2.3.4/32
set protocols bgp group ibgp type internal
set protocols bgp group ibgp local-address 10.101.12.245
set protocols bgp group ibgp family inet-vpn unicast
set protocols bgp group ibgp neighbor 10.101.0.254 local-as 64512
set protocols ospf area 0.0.0.1 interface lo0.0
set protocols ospf area 0.0.0.1 interface ge-0/0/47.0
set protocols ldp interface ge-0/0/47.0
set routing-instances one instance-type vrf
set routing-instances one interface lo0.1
set routing-instances one route-distinguisher 10.101.12.245:1
set routing-instances one vrf-target import target:1:1
set routing-instances one vrf-target export target:1:1
set routing-instances one vrf-table-label


explained as i understand it....

P-facing core interface...
set interfaces ge-0/0/47 mtu 9192
set interfaces ge-0/0/47 unit 0 family inet address 10.101.14.118/30
set interfaces ge-0/0/47 unit 0 family mpls

set interfaces lo0 unit 0 family inet address 10.101.12.245/32

PE-CE test interface...
set interfaces lo0 unit 1 family inet address 1.2.3.4/32

MP-BGP label signalling mechanism for advertising VPNV4 label between pe's...
set protocols bgp group ibgp type internal
set protocols bgp group ibgp local-address 10.101.12.245
set protocols bgp group ibgp family inet-vpn unicast
set protocols bgp group ibgp neighbor 10.101.0.254 local-as 64512

IGP routing ... you need to be able to FIRST learn the remote PE's loopback in order to route to it...
set protocols ospf area 0.0.0.1 interface lo0.0
set protocols ospf area 0.0.0.1 interface ge-0/0/47.0

set protocols ldp interface ge-0/0/47.0

MPLS L3VPN config...
set routing-instances one instance-type vrf
set routing-instances one interface lo0.1
set routing-instances one route-distinguisher 10.101.12.245:1
set routing-instances one vrf-target import target:1:1
set routing-instances one vrf-target export target:1:1
set routing-instances one vrf-table-label

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?
