    when HTTP_REQUEST {
	if { [active_members [LB::server pool]] == 0 } {
		node remote-vs-ip port
	}
}

    Example:

    when HTTP_REQUEST {
	if { [active_members [LB::server pool]] == 0 } {
		node 10.11.12.13 443
	}
}

      But the VS which needs to be redirected is not configured in the same LB. It is configured in the remote peer

    Thanks  redirection happened but got into another issue.

     

    We have SAML / SSO auth enabled. When the traffic hit the VIP, it got redirected to the other VIP, from the backend server it went to the auth & again got loaded back to the 1st VIP itself, kinda creating a loop.

     

    Any suggestions for this.
