Creates a L3 leaf-spine topology with VXLAN via eos_template role in Ansible 2.1+

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

http://ansible-eos.readthedocs.io/en/master/quickstart.html

UNDER DEVELOPMENT

v0.2

• Still testing, fixed indentation to align to eos_template requirements
• MLAG/VXLAN functionality appears buggy in vEOS under unetlab - may require restarting individual hosts in MLAG pairs, behaviour is inconsistent - believe this to be related to virtual lab (i.e. the provisioned configuration is correct if run on hardware)

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
  • VLAN20 on Po6 (Ethernet6) on all leafs

• VXLAN

  • VLAN10 = VNI 1010
  • VLAN20 = VNI 1020
  • logical VTEPs on Lo1

• NO vVTEP or anycast GW - hosts are L2 only via VXLAN
