1.I have two sites A and B
2.Both sites are connected by means of 512 KB Leased line through internet.
3.I have RF link also connecting these two sites through Internet.
4.Now I have created a Site-to Site VPN between these sites through serial interface.
5.I have configured the GRE tunnel between these two sites using the RF link
6.My requirement is a)load sharing between the RF and serial interface b)failover between interface
7.Is it possible to have load sharing through VPN tunnel?
8.Is it necessary to have same ISP? or is it possible through different ISP?
Thanks and Regards,
