Abstract
A local spoke is configured with a hub that serves at least one remote spoke equipped with a plurality of IPSEC endpoint interfaces for routing traffic according to a routing table of the hub. A first routing path is received to the at least one remote spoke for dynamic VPN with a first IPSEC endpoint selected by the hub based on a Reply message without consideration of first link quality of the remote spoke relative to other available links. In another embodiment, an ADVPN shortcut is established. Data packets are then transmitted using a second routing path for dynamic VPN with a second IPSEC endpoint. A new ADVPN shortcut is established for more optimal routing, based on updated link quality metrics discovered during a health check. The existing ADVPN shortcut is then allowed to expire.
