Network

From NURDspace

Layer 2 overview

Below you can find the structure of the network as of 10-04-2022. Fat lines are LACP trunks Layer 2 overview 06-05-2022.svg

Layer 3 overview

we have a single-vlan flat network. Due to legacy, three different prefixes live on this vlan:

  • 10.208.11.0/24 (gateway 10.208.11.1)
  • 10.208.30.0/24 (gateway 10.208.30.1)
  • 10.208.42.0/23 (gateway 10.208.42.1)

This has the issue that traffic between the vlans will always be routed via the gateway, leading to unneeded roundtrips.

IP addresses

  • 10.208.30.0/24 is used for static allocations. Register your ip's in IPAM.
  • 10.208.42.0/23 is used for dynamic allocations using DHCP

DNS

search nurd.space lan.nurd.space vm.nurd.space management.nurd.space router.nurd.space dhcp.nurd.space
nameserver 10.208.30.254

Layer 3 simplification

In order to reduce the unnescecary roundtrips via the edgerouter, we need to flatten the networks into a single prefix. The proposal for this is to move to 10.208.28.0/22. This prefix would be used as follows (With the gateway living on 10.208.30.1):

  • 10.208.28.1 .. 10.208.29.255 DHCP
  • 10.208.30.1 .. 10.208.30.255 Static clients
  • 10.208.31.0 .. 10.208.30.254 reserved
