FlexVPN supports dynamic routing protocols to ensure failover redundancy and efficient routing over VPN tunnels.
The two main protocols used for this purpose are OSPF (Open Shortest Path First) and EIGRP (Enhanced Interior Gateway Routing Protocol).
- OSPF is widely used for dynamic routing in enterprise networks and can establish adjacencies over FlexVPN tunnels.
- EIGRP is also supported and provides faster convergence, making it a preferred option for failover scenarios.
