Thanks Salvatore. As a resolution, is it only to change the configuration from main-interface to sub-interface p2p？ If it is only sub-interface p2p, when and how should I use main-interface frame-relay configuration ? Don't you usually use main-interface frame-relay configuration ? Is there any solution by using current(main-interface) configuration to resolve my problem ? If there's something good to see, please let me know the URL or book.
Thanks.
