arista-config

Creates a sample 2 x spine and 4 x leaf L3 topology with VXLAN via arista.eos role in Ansible 1.9+

Tested with vEOS 4.15.5M in Unetlab 1.0.0-12 and Ansible 1.9, 2.1

NOTE: MISSING ECMP SETTING IN BGP

SAMPLE TOPOLOGY VARIABLES

• routed
• eBGP - spine AS 65000, leaf1/2 AS65001, leaf3/4 AS65003
• MLAG
  • Peer-link on Po1, VLAN4094
  • iBGP on Po1, VLAN4093
• Host attachment via MLAGs
  • VLAN10 on Po7 (Ethernet7) on all leafs
