HeadQ is connected 9 Branch office with GRE over IPSEC running EIGRP on WAN and OSPF on LAN.
HeadQ=Hub is single point of failure with One Service Provider and Single piece of hardware. We are moving slowly, planned to get another Internet connection from another Service Provider.
Terminating Two Service provider as sub interface at HUB, is this best practice from cisco. Would this impact two tunnels from Hub facing same spoke with different service provider.
Need to make it simple, workable, redundant.
