- | bennachie.57n.dn42 is an apu3c4 board running OpenBSD. It terminates the PPPoE tunnel from Converged and has a 2G LACP trunk into the core switch in the same rack. This trunk uses 802.1Q encapsulation to carry multiple VLANs as detailed below. | + | The router is at router.hl.57north.net.uk. IPv4: 172.23.152.254. IPv6: 2a11: |

- | In the event of a failure, the configuration for this box is backed up to an SD card. This card appears as `/dev/sd1i` and is mounted normally at `/sdcard`. This is FAT formatted, not FFS, so it is possible to just plug this into whatever to read the contents. On this SD card you'll find a readme and a tar file containing the contents of /etc. | + | ===== DHCP / RA ===== |

- | do the right thing with them. | + | |

- | Step 3: Packages | + | |
- | ---------------- | + | |
- | + | ||
- | Other than the base system, some packages are configured: | + | |

- | + | ||
- | Packages are not critical to the operation of the router. As far | + | |
- | as possible we should use only the base system to make it easier | + | |

- | When considering new IP ranges, it is necessary to consider which ranges would already be in use in ChaosVPN, dn42 and Freifunk. The range 192.168.0.0/ | + | |
- | + | ||
- | Some blocks in this table have been marked as legacy. This is because the addressing they use was from ChaosVPN, and we are now instead looking at dn42 for inter-hackerspace peering. ChaosVPN and dn42 co-ordinate on address space and also peer with each other and so we should not be losing any connectivity. | + | |
