NOTE: Consider the following:

  • The two nodes must have different Interface IP.

  • If you do not use next hop monitoring on the redundant interface, you can use any Interface IP (even if otherwise it does not exist on that network).

  • If you use next hop monitoring on the redundant interface, the Interface IP address must be a real IP address that is visible from the other node.

  • If you use next hop monitoring on the redundant interface, the Interface IP must be accessible from the next-hop address, and vice-versa. For details on next hop monitoring, see Next-hop router monitoring.
