The whole problem of the update via RIP2 was the ISP modem that blocks multicast RIP??? although saw the RIP packets incoming on JNOS monitor screen from UCSD amprgw. The modem with this problem is SENDTEL ADSL2 + Router MS8-8817 which I have changed to another ADSL brand (StartBridge) now working perfect the encapsulation and RIP update.

The RIP2 updates are IPIP encapsulted, so from the ISPs point of view they are protocol 4 (IPIP) frames. They become RIP2 multicasts only AFTER being decapulated by the tunnel interface. So, unless your ISP blocks protocol 4, there is no issue with these broadcasts. The fact that you see them in your JNOS monitor is proof that IPIP proto 4 is not blocked.
