Hi Guys,
I am totally confused now. I have the following topology:
R1 --- OSPF (Area 0) ----CE --- OSPF (Area 51) --- R5 ----- MBGP ------ R4
---- OSPF (Area 1) --- CE ---- OSPF (Area 1) ---- R2
R5 = R4 = PE
>From left to right:
I have configuredf a virtual-link from CE to R5. R5 to R4 a sham-link.
Configuration is as follows:
R5:
router ospf 18 vrf vpn30
router-id 30.30.5.5
log-adjacency-changes
area 0 sham-link 30.30.100.5 30.30.100.4 (the loopback interfaces that are
NOT advertised into OSPF but only BGP)
area 51 virtual-link 30.30.7.7
network 30.30.0.130 0.0.0.0 area 51
R4:
router ospf 9 vrf vpn30
router-id 30.30.4.4
log-adjacency-changes
area 0 sham-link 30.30.100.4 30.30.100.5
network 30.30.128.130 0.0.0.0 area 1
Loopback for R1 = 30.30.1.1
Loopback for R2 = 30.30.2.2
Now here is what I think should be happening, since different Process IDs on
both R4 and R5, IOS will treat them as differ domain-id and hence the route
when taken from the remote CEs should be E2 routes where as I see them as
follows:
R4(config-router)#do sh ip route vrf vpn30 30.30.1.1
Routing entry for 30.30.1.1/32
Known via "ospf 9", distance 110, metric 22, type *intra area
* Last update from 30.30.5.5 00:09:40 ago
Routing Descriptor Blocks:
* 30.30.5.5 (Default-IP-Routing-Table), from 30.30.1.1, 00:09:40 ago
Route metric is 22, traffic share count is 1
R5(config-router)#do sh ip route vrf vpn30 30.30.2.2
Routing entry for 30.30.2.2/32
Known via "ospf 18", distance 110, metric 32, type *inter area*
Last update from 30.30.4.4 00:10:04 ago
Routing Descriptor Blocks:
* 30.30.4.4 (Default-IP-Routing-Table), from 30.30.4.4, 00:10:04 ago
Route metric is 32, traffic share count is 1
No matter what I do, if I change the process IDs at both R4 and R5 to be
similar, the routes remain the same. I have tried using same process ID
with different domain-id too but to no avail. Can anyone point out my
mistake here? With different Proccess ID I expect the routes to be E2.
Sorry for bringing this up again.
Regards,
