Open Infrastructure

Step 1: routing setup¶

• Accept all networks from upstreams and ungleich peers
• don't announce any network
• full routing table in kernel
• no ip hacks (dummy0, lo)
• do we still need to solve the "next hop self ebgp;" problem with bird2?
  • bird2 will reject announcements from routerX peers in ungleich
  • bird2 will accept announcements from upstreams (direct)
  • bird2 to bird2 will accept due to rewrite

• Announcing 2a09:2942::/32 only via netstream makes it unreachable
  • Announcing it to router1.place5 makes it instantly reachable

At this stage the router is fully able to do IPv4 and IPv6 routing

Step 2: add some traffic¶

• add the IPv6 address of the coworking network -> go active-active

Step 3: add nat64 w/ jool + joold¶

• setup jool+joold for "masquarding" 1:n sessions to .1 IPv4 address

Step 4: Announce test network (IPv4, IPv6)¶

• Something non-productive
• ensure routing works
• Maybe spin up VMs and/or end hosts in that network

Step 5: announce all networks to upstreams and peers¶

• final step for back in production
• at this point router2.place6 can be reinstalled/replaced
  • repeat all steps from here
