—– Original Message —– From: “Victor” Sent: Tue, July 14, 2009 19:39 Subject:OSPF Virtual Links and PPPoFR
Hello Guys, I’ve been trying to get running OSPF Virtual Links over a 3 routers topology 1 hub + 2 spokes using PPPoFR for connecting between them, where one of the spokes is the backbone and I have some Loopbacks created on each router on different areas, so finally I only can get running the Virtual Link going from spoke to spoke but NEVER the VL between the hub to the spoke (area 0). I changed the PPPoFR config and used only FR and everything works OK, when I try to use PPPoFR (no changes in OSPF config) I get the same problem.
I’m sure I’m missing something….. do you have any suggestion??
Regards…. Victor.

The Type-5 LSA is originated by the ASBR R3 (Router-ID:172.30.0.1). And the forward address would be 0.0.0.0, indicating to forward traffic for that prefix to the ASBR itself. If you do a show ip ospf border-router on R2, you’ll see it has an intra area route to R3 (Router-ID:172.30.0.1) over E0/1. When you shutdown the E0/1 interface R2 loses it’s intra area route to the ASBR, it will in turn have an inter area route to the ASBR via R1.
So as long as there is the intra-area route to the ASBR on R2, i.e since ospf process on R2 finds both an intra area route and inter area route to the ASBR, it will ignore the cost and simply choose the intra area route to the ASBR.

I’m trying to figure out why manipulating interface OSPF cost does’t change the path to get to a network on a scenario like this:
172.30.0.0/20 R3 /B B B B B B R1 — R2
R1-R3 - Area 10 R2-R3 - Area 10 R1-R2 - Area 0
Increasing OSPF cost on path R2->R3 should’t R2 prefer R1 to get to 172.30.0.0/20 ?
R2#show ip route 172.30.0.0 Routing entry for 172.30.0.0/20, 1 known subnets
O E1B B B 172.30.0.0 [110/30] via 172.29.4.33, 00:00:01, Ethernet0/1
After changing Cost to 1000, R2 still prefers same path, even with a higher cost:
R2#conf t Enter configuration commands, one per line.B End with CNTL/Z. R2(config)#int et 0/1 R2(config-if)#ip ospf cost 1000 R2(config-if)#^Z R2#show ip route 172.30.0.0 Routing entry for 172.30.0.0/20, 1 known subnets
O E1B B B 172.30.0.0 [110/1020] via 172.29.4.33 , 00:00:10, Ethernet0/1B B OSPF network 172.29.4.33 0.0.0.0 area 10 network 172.29.4.49 0.0.0.0 area 10
route-map CONN->OSPF permit 10 match interface Loopback0

I changed the PPPoFR config and used only FR and everything works OK, when I try to use PPPoFR (no changes in OSPF config) I get the same problem.
I’m sure I’m missing something….. do you have any suggestion??
Regards…. Victor.

Created a second cco register, disasociated my true ID (which has my CSCO id) from the company (by the way, it’s instantaneous but the guy responsible for the relationship with Cisco receives also an instant communication) so in this register I’ve no longer partner access. After that I requested association to the company with my second cco id, that’s all. I’m lucky because nobody asked anything but I decided to take the risk.
Thanks everyone….. Victor

I’d put it this way; “show interface switchport” for 3560/3750 platforms has some misleading/missing lines. Since this is a minor disadvantage and there is a way to verify what actually is happening, it has probably escaped quality assurance testers’ attention. Another possible reason for having “Administrative” for this as enabled might be in original idea of having a global “vlan do1q tag native” enabled by default which didn’t happen.
If you are so keen on finding the real one, you can try and open P4 case with TAC, we’d love to hear the story. :-)
