For general information on setting up hierarchical proxies, refer to Chapter 10 Proxy Routing in the RealProxy Administration Guide.
If there is a transparent service configured for a parent proxy, you must configure an RTSP port other than 554 for parent proxy. The Parent RTSP port parameter in all routing rules referencing this parent proxy must be set with the same port number. Proxies do not support redirection.
IMPORTANT: Never configure the origin server as the parent in a routing rule. This can cause unpredictable results.
