Cisco Cisco Dynamic Fabric Automation for OpenStack Leaflet

Page of 80
After you configure the second border leaf pair, the following changes occur:
• All border leafs start to respond to Address Resolution Protocol (ARP) with anycast-gateway MAC
addresses.
• Direct forwarding occurs between the border leaf pairs, without going through the Cisco Nexus 7000
Series switch.
The unicast traffic flow and north-south traffic remains unchanged.
What to Do Next
Upgrade the software for the FabricPath leaf pair.
Step 6: Upgrading the FabricPath Leaf Pair
You can perform an in-service software upgrade (ISSU) for the FabricPath leaf pair.
Step 1
Upgrade the leaf node from Cisco NX-OS Release 6.0.(2)N2 to Cisco NX-OS Release 7.0.(0)N1(1) using an ISSU
upgrade procedure. See the
for
information on performing an ISSU upgrade
Step 2
Verify that the first leaf comes up fully and becomes operational again.
Step 3
Make sure traffic streams are already running intra-VLAN, inter-VLAN, across pods, and that north-bound traffic remains
unaffected.
Step 4
Repeat Steps 1 to 3 for the second border leaf node in the pair.
There is no change in the traffic flow.
What to Do Next
Configure the border leaf pair with Cisco Dynamic Fabric Automation.
Step 7: Adding the Cisco DFA Configuration to Layer 2 Leaves
You can configure the FabricPath leafs in the network.
For specific configuration commands and examples, see
.
Note
Before You Begin
Before you configure the Fabric Path leaf, you should upgrade the software.
Step 1
On the first switch in the pair, do the following:
a) Install a Layer 3 license.
