This directory contains the script used on the remote host that emulate exchange points and hosts VMs running the virtual network from the parent directory.
See ./net_manager.sh --help for instructions.
Notable features:
- Port forward host TCP ports 40000+ to guests port 22 (SSH forwarding)
- Guest are dual homed
- Partial Tear up/down is mostly safe (and a lot is reentrant)
- NAT64/DNS64 done by the host (DNS is operated at fd00::d)
- Dual-stack iptables masquerade
- IPv4 traffic is blocked at the POPs
- Guest VMs can peer between one another
- Sample BGP looking glass available within the emulated network to let groups
examine the status of the BGP peerings (available at
http://belneta.ingiandhttp://belnetb.ingi, provided the DNS servers are setup properly).
