BGP between VMs

[Chriztoffer Hansen]

Fabiano,

RTFM is the short answer, (not trying to be rude here 😜)

EBGP between two bgp speakers (eg. VMs) is rule of thumb done using
interfaces on each ebgp speaker in a shared L2 domain, with ip addresses on
each interface in a shared subnet, eg. Ipv4 /30, /31, IPv6 /64, /126, /127.
If both VMs are on the same hypervisor. A virtual L2 network between VM
interfaces is the easiest option to get going. 😉
