> ICP is broken in all the releases and master, but we have options for that:
> inter-colo peering to use the parent.config, local network peering to use the
> cluster.
> refer to the official docutments for parent.config and cluster howto.

> The ICP implementation in Traffic Server broke when epoll() was introduced.
> Its still an interesting and used feature in caches:
> - when a caching layer of several boxes are used ICP helps to reduce
> disparities when a client is not routed to the same cache on subsequent
> requests
> - after a restart, it can help reduce the time spent in a cold cache situation
