cRTP changes the packet header and, therefore, must be decompressed before routing can take place. This makes cRTP a hop-by-hop protocol, with decompression and recompression occurring in every routing node in which the feature is enabled and with using GRE also you will lose GRE headers so you need L2 PVC between CPEs.
