Core node group setup¶
The following page explains how to set up a group of core nodes.
A node group allows you to treat a group of nodes as if it were a single node. The most common use case is to set a group as the target of a peer connection, facilitating quick and seamless failover if one of the nodes in the group goes down. More information can found in the node group documentation.

Instructions¶
Create a new node group record on the management server with the name
West.Create a new node record on the management server with the name
dc0and the node groupWest.Add an interface to the
dc0node record with the following configuration:Name:
eth0Aliases:
publicVRF:
GlobalIPv4:
203.0.113.1/24IPv6:
2001:db8:1::1/64Keep on shutdown enabled on both addresses
Create another node record on the management server with the name
dc1and the node groupWest.Add an interface to the
dc1node record with the following configuration:Name:
eth0Aliases:
publicVRF:
GlobalIPv4:
203.0.113.2/24IPv6:
2001:db8:1::2/64Keep on shutdown enabled on both addresses
You now have a valid core node group configuration ready to accept peer link connections from other nodes.
