Yes and default value is set to IPv4 in line 80.

- ipv6={{ ipv6|default(false) }}

It doesn't sound right to me. We have announced the next-hop of the route as VLAN. Shouldn't expect packets on Portchannels. We might need to change both ipv4 and ipv6 to VLAN here.

I tested it locally, I think we also need to config the ips of two mux on PTF host to make sure it will not use default route.

one example: In in exabgp/start.sh template, to config one mux_ip: ifconfig eth{{ '%d' % (minigraph_vlans[minigraph_vlan_interfaces[0]['attachto']]['members'][1] | replace("Ethernet", "") | int / 4)}} {{item.mux_ip_1}}
