Remote Leaf || Cisco ACI || Why only OSpf

[saurabh_gera]

Hi Team, 

Why cisco suggested only OSPF for remote leaf extension, Shouldn't the whole idea be to have IP backbone reachable fo extension. 

We dont run OSPF on any switches , what other options are vailable BGP or EIGRP or  Static DR ?

Hi Saurabh,

From ACI 5.2(3), we've supported BGP for underlay connection. You can refer below docs. 

Changes For Release 5.2(3)
Beginning with Cisco APIC release 5.2(3), the following changes have been applied for remote leaf switches:
• The IPN underlay protocol to peer between the remote leaf switches and the upstream router can be either OSPF or BGP. In previous releases, only an OSPF underlay is supported.
