I have exactly same problem. Here is my simply setup:
R1(PE,Cisco, lo 1.1.1.1)---R2(P, Cisco, lo 2.2.2.2)--R3(PE, OpenBSD6.1, lo0
3.3.3.3)
Everything works good, VPNv4 prefixes learned from other PE-router, but
OpenBSD don't install this routes to appropriate routing table.
Here is config files:
# cat /etc/ospfd.conf
router-id 3.3.3.3
area 0.0.0.0 {
interface vio1
interface lo0
}
# cat /etc/ldpd.conf
address-family ipv4 {
interface vio1
}
# cat /etc/bgpd.conf
router-id 3.3.3.3
AS 100
rdomain 1 {
descr "CUSTOMER1"
rd 100:1
import-target rt 100:1
export-target rt 100:1
depend on mpe0
network inet connected
}
group ibgp {
announce IPv4 unicast
announce IPv4 vpn
remote-as 100
local-address 3.3.3.3
neighbor 1.1.1.1 {
descr R1
}
}
Here is my output:
