    Hi All,

     

    Just want to know if anyone here has experience implementation IP CLOS Fabric when Spine is "Juniper" but Leaf is "Cisco or Arista". Is it compatible VXLAN between of them because Juniper really like use EVPN for VXLAN but others vendor not compulsory using EVPN.

     

     

    Thanks and appreciate any input.

    There is no compatibility issue between vendor as far as IP CLOS implementation is concerned. You can use Juniper as Spine and any other vendor as Leaf there should not be any problem. IP close is just L2 point to point connectivity between spine and leaf which is supported by all vendors.

     

    For VXLAN implementation Juniper does support Manual VXLAN as well as VXLAN with EVPN as overlay. You can refer to the below doc for VXLAN implementation on Juniper.

     

    https://www.juniper.net/documentation/en_US/junos/topics/topic-map/sdn-vxlan.html 

     

    if you are using VXLAN I would suggest to use EVPN as overlay as it is supported on all vendor platforms who support vxlan.

    Hi Kronicklez,

     

    I have seen setup like that working fine. in case you are planning for ERB then spine hardly has any role to play as it would just be paas through device doing L3 routing and does not have to be part of vxlan unless you decide to terminate the traffic going out of the network (internet) on spine itself instead of external security gateways.

     

    in case of CRB it works fine as L3 gateway.
