Single LAN edge deployment with failover¶

The following page explains how to set up an edge node deployment with failover capability, connecting to both a primary and secondary remote node or node group.

Instructions¶

Follow the instructions to set up two core nodes dc0 (primary) and dc1 (failover), with the following interface configuration on dc1:
- Name: eth0
  - Aliases: public
  - VRF: Global
  - IPv4: 192.0.2.1/24
  - IPv6: 2001:db8:2::1/64
  - Keep on shutdown enabled on both addresses
Create a new node record on the management server with the name cpe0.
Add the following interfaces to the newly created node:
- Name: eth0
  - Aliases: lan0
  - VRF: Global
  - IPv4: 198.51.100.1/24
  - IPv6: 2001:db8::1/64
  - Keep on shutdown disabled
- Name: eth1
  - Aliases: wan0
  - VRF: No VRF
  - IPv4: DHCP
  - Keep on shutdown enabled
- Name: eth2
  - Aliases: wan1
  - VRF: No VRF
  - IPv4: DHCP
  - Keep on shutdown disabled
Next, add a peer to the node with two remote targets:
- Name: Default
  - Interface: eth1 (Preference: 500)
  - Interface: eth2 (Preference: 500)
  - Remote (node): dc0 (Preference: 500)
  - Remote (node): dc1 (Preference: 400)
Then, add a nexthop to the node:
- Type: Peer
  - Peer: Default
Finally, add two routes to the node:
- Destination: 0.0.0.0/0
  - VRF: Global
  - Nexthop: Default (Preference: 500)
- Destination: ::/0
  - VRF: Global
  - Nexthop: Default (Preference: 500)
You now have a complete edge node configuration forming a peer connection with a remote node with failover to a secondary remote node.

Instructions¶

Follow the instructions to set up two core node groups West (primary) and East (failover). For the East node group, call the first node dc2 and give it the following interface configuration:
- Name: eth0
  - Aliases: public
  - VRF: Global
  - IPv4: 192.0.2.1/24
  - IPv6: 2001:db8:2::1/64
  - Keep on shutdown enabled on both addresses
In the same node group, call the second node dc3 and give it the following interface configuration:
- Name: eth0
  - Aliases: public
  - VRF: Global
  - IPv4: 192.0.2.2/24
  - IPv6: 2001:db8:2::2/64
  - Keep on shutdown enabled on both addresses
Next, follow the instructions for connecting to a secondary failover node, but when configuring the peer, set the remote targets to the two node groups you created.
