Hi Serghei
Can you confirm with a "show route extensive 0.0.0.0 instance VRF-B" the
details of the route received.
I have just build a litte lab with your config with logical routers (not
virtual ones ... Vrf)
I have the same ditribution filters as the one you're describing:
policy-statement EXPSTA {
term 1 {
from {
route-filter 0.0.0.0/0 exact;
}
then reject;
}
term 2 {
from {
protocol static;
route-filter 10.11.12.0/24 exact;
}
then accept;
}
}
And I don't see the behaviour you're describing... I have default route
received via bgp on router B distributed to router A and a static route
10.11.12.0 distributed from router A to B.
I think like wrote tonny we defenitely need some more config or traces from you.

Objet : [j-nsp] New post: OSPF export policing
Hi All. I have unwanted 0.0.0.0/0 route from OSPF peer. I have problems with
route export in an OSPF area.
I have 2 Juniper boxes.R1 and R2 with several vrf-instances in each of
them(with different OSPF area in different pairs of vrf)
Now I'm making new VRF in each of Routers. VRF-A in R1 and VRF-B in R2. and
I'm configuring OSPF area 0.0.0.5 between VRF-A and VRF-B (in separate VLAN).
I need to export only 10.11.12.0/24 static route through OSPF from VRF-A to
VRF-B
And I need to export only 0.0.0.0/0 BGP route through OSPF from VRF-B to VRF-A.
I'm using route policy to OSPF export. I have installed my 10.11.12.0/24 static
route in VRF-B from OSPF VRF-A. And I have 0.0.0.0/0 in VRF-A from VRF-B.
!!! But, I also have 0.0.0.0/0 static route in VRF-B from OSPF VRF-A ??? Why
?? I don't have any static 0.0.0.0/0 in VRF-A
I have static 0.0.0.0/0 only in other VRF in R1.
my OSPF export policy on R1 VRF-A is:
term 1
from route-filter 0.0.0.0/0 exact
then reject
term 2
from protocol static
route-filter 10.11.12.0/24
then accept
In OSPF Trace from R1(VRF-A) I see that R1 uses transit area 0.0.0.0 to export
static 0.0.0.0/0 but I don't have area 0.0.0.0 in R1.
I have area 0.0.0.0 only between router R2 and another R3.
Please, If someone can to suggest some idea . Thank You
Best regards
