EVPN with IP Fabric - VLAN IP Prefix question

‎10-14-2016 04:12 AM

Hi

 

Am setting up an IP fabric with VXLAN/EVPN on the qfx5100 series.

 

It states in network director that each leaf needs a subnet ( VLAN IP Prefix )

 

Specify the IP address block that will be reserved for the virtual machines or hosts that will be connected to the leaves.
Network Director allocates each leaf device with a subnet from the given IP address block.

 

As each leaf is a standalone BGP router in IP fabric, how does this work for hosts that are using a lag to connect to two leafs?  the network would belong to a single leaf yet a /32 would be on the other leaf.

I assume that I would be redistributing into BGP the /32s of each host from each leaf?

 

or is this only for management of the hypervisor?

 

not a lot of detail on this part in the design guides?

 

any feedback gratefully accepted.

 

thanks
