A method of realizing Dmvpn two-center main standby Path

I. DMVPN Tan Yun Double Center

A. By modifying the OSPF cost value of the two-center tunnel interface, only the routers behind the center will be routed to spoke

B. By modifying the OSPF cost values for the physical interface behind the two centers, you can influence spoke select different hubs to the network behind the center

C. Because there is only one virtual tunnel, it is not possible to implement a different hub by adjusting the OSPF cost of the spoke tunnel interface to the network behind the center

D. If the virtual tunnel is running EIGRP Dynamic routing protocol, spoke can choose the path by distance command

Two. Dmvpn Double Cloud Double Center

A. Similarly, by modifying the OSPF cost value of the two-center tunnel interface, only the routers behind the center are routed to spoke

B. Similarly, by modifying the OSPF cost values for the physical interface behind the two centers, the spoke can be affected by selecting different hubs to the network behind the center

----then spoke to spoke's internal network will have two equivalent paths, separate virtual tunnels.

C. Because there are two virtual tunnels, you can adjust the OSPF cost of the spoke tunnel interface to realize the different hub to the network behind the center

----then spoke to spoke's intranet network with the lower cost of the virtual tunnel path

D. Similarly, if the virtual tunnel is running on a EIGRP dynamic routing protocol, spoke can select the path through the distance command
