Removing a route-domain may cause icmp and gateway-icmp monitors in unrelated route-domains to fail.
Monitor marks the node down, resulting in partial service outrage.
-- Route-domain is removed. -- icmp/gateway-icmp monitor is used.
Restart bigd using the following command: bigstart restart bigd
Removing route-domain no longer causes monitors to fail.
