Network Connection Reset

Problem

This section describes how to resolve the network connection reset issue in Geographical Redundancy (GR) deployment.

During GR deployments, the SMI Cluster Manager is deployed on one or more remote sites. When the SMI Cluster Manager is deployed in at least two remote sites and if those deployed SMI Cluster Managers use a common Vrrp-router ID over a common VLAN/network with different IPs for running the traffic on SBI interface, the network connection resets with the following error:

Network error connection resets by peer

Resolution

The network connection resets because the Virtual IP (VIP) router ID is not unique across the two SMI Cluster Managers. You must ensure that the VIP router ID is unique while configuring the K8s clusters. For more details on configuring the cluster, see Clusters Configuration section in UCC SMI Operations Guide Guide.
