Hello,
Maybe I am wrong, but as long as R1,R3,R4 are internal bgp neighbors,
R4 should be route reflector for R4.

Hi guys,
Now I'm preparing for JNCIE-SP certification, and faced with problem providing
internet-access for VPN users.
I attach my test topology to email.
R4 and R3 are PE routers which holds vrf table "Customer", R1 router holds ipv4
static route 8.8.8.8/32 to represent Internet routes. Between R4 and R3 there is vpnv4
IBGP session and Between R4 and R1 - ipv4 IBGP.
I use rib-group to import IPv4 routes received from R1 also in table
Customer.inet.0. Routes are imported as expected and I see 8.8.8.8/32 in vrf
Customer:
R4# run show route table Customer 8.8.8.8
Customer.inet.0: 4 destinations, 4 routes (4 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
8.8.8.8/32 *[BGP/170] 00:50:35, localpref 100, from 172.27.255.1
AS path: I
> to 172.27.0.10 via ge-1/3/0.41, label-switched-path
r4-to-r1
[edit]
R4@M7i-2#
But the problem is that R4 doesn't pass this route from VRF to R3 via MP-BGP.
R4@M7i-2# run show route advertising-protocol bgp 172.27.255.3
Customer.inet.0: 4 destinations, 4 routes (4 active, 0 holddown, 0 hidden)
Prefix Nexthop MED Lclpref AS path
* 2.2.2.2/32 Self 100 1 I
* 172.27.0.4/30 Self 100 I
[edit]
R4@M7i-2#
The same task was in bootcamp lab guide book, and according to it, other
members of VRF do receive internet routes. I also tried to use VRF export
policy;vrf-table-label - nothing helps.
Please help, may be there is some knob to make it work?
PS:All routers are real equipment (no logical systems).
PSS:I also attach relevant parts of config.
