According to the APIC-EM overview in the southband section; The use of the CLI ensures that APIC EM works with your existing Cisco legacy products. Future versions of APIC EM will leverage other southbound technology such as onePK, OpenFlow, and other device APIs as they are implemented. So to me it look like that APIC-EM will make use of onePK so I assume it would still be supported on the devices for a while. Fabrice ... View more

Thanks Brett, If I get correctly I can acheive this using APIC EM SDN controller but 1) The product is not available yet for general public? 2) When it will come out it will only be supported on Cisco UCS (not possible to install it on Ubuntu Server)? Thanks, Fabrice ... View more

Thanks, It would be interesting to know why is that? I do understand that you would not want to do that for neighboring but for simple network annoucement, I don't see an issue with it really. ... View more

Hi Guys, Thanks for your answers, however I fear that I have not been understood. Agreed with you LA, I am not trying to establish neighbor for two OSPF process on same interface, this is not supported. I can't put production config here but I have writen a sample configuration. Please note that it is not applied to any devices so won't be able to produce any output commands this is just to give you a better idea.   Router A ! interface Loopback0  description MGNT Interface  ip address 1.1.1.1 255.255.255.255 ! interface GigabitEthernet1/1   description User LAN   ip address 192.168.1.1 255.255.255.0  !  interface GigabitEthernet1/10   description To router B fo OSPF 10 ONLY   ip address 10.1.1.1 255.255.255.252 ! interface GigabitEthernet1/20   description To router B fo OSPF 20 ONLY   ip address 20.1.1.1 255.255.255.252 ! router ospf 10   router-id 10.1.1.1  log-adjacency-changes  passive-interface default  no passive-interface GigabitEthernet1/10  network 10.1.1.0 0.0.0.3 area 0  network 1.1.1.1 0.0.0.0 area 0  network 192.168.1.0 0.0.0.255 are 0 ! router ospf 20   router-id 20.1.1.1  log-adjacency-changes  passive-interface default  no passive-interface GigabitEthernet1/20  network 20.1.1.0 0.0.0.3 area 0  network 1.1.1.1 0.0.0.0 area 0  network 192.168.1.0 0.0.0.255 are 0  distance 150 Router B ! interface GigabitEthernet1/10   description To router A fo OSPF 10 ONLY   ip address 10.1.1.2 255.255.255.252 ! interface GigabitEthernet1/20   description To router A fo OSPF 20 ONLY   ip address 20.1.1.2 255.255.255.252 ! router ospf 10   router-id 10.1.1.2  log-adjacency-changes  passive-interface default  no passive-interface GigabitEthernet1/10  network 10.1.1.0 0.0.0.3 area 0 ! router ospf 20   router-id 20.1.1.2  log-adjacency-changes  passive-interface default  no passive-interface GigabitEthernet1/20  network 20.1.1.0 0.0.0.3 area 0  distance 150   Now if you look on Router B you will not see network 1.1.1.1 & 192.168.1.0 under the OSPF process 20 database if you have entered the network command on OSPF 10 first on Router A. If you look on Router A with "show ip ospf int brief" you won't even see interface Loo0 and Gi1/1 listed. After tresting around it seems that I can't have both of those network present in both database, whatever I try. If I want have those networks present in OSPF 20 I have first to remove them from OSPF 10 and then put them on OSPF 20. I just wanted to know if this is normal behaviour or not?   Thanks,         ...

Thanks to all for your input. I can definitely see that that architech is not for me at least for a few years (until I get bored with conf t), I also don't have the skills listed above. As for design it will depend on where I end up working for. Thanks, Fab ... View more
