If the addresses of the tunnel interfaces at the two ends of a tunnel are not in the same network 

segment, a forwarding route through the tunnel to the peer must be configured so that the 

encapsulated packet can be forwarded normally. You need to configure a static or dynamic route at 

both ends of the tunnel. For the detailed configuration, refer to Static Routing Configuration or other 

routing protocol configuration in the IP Routing Volume.  

z 

The IPv4 address and the destination address of a tunnel interface cannot be in the same network 

segment. 

z 

The destination address of a route with a tunnel interface as the egress interface and the 

destination address of the tunnel interface must not be in the same network segment. 

z 

Two or more tunnel interfaces using the same encapsulation protocol must have different source 

and destination addresses. 

z 

If you specify a source interface instead of a source address for the tunnel, the source address of 

the tunnel is the primary IP address of the source interface. 

z 

When you configure dynamic routing at each tunnel end, you need to enable the dynamic routing 

protocol on the tunnel interface. For related configurations, refer to related contents in the IP 

Routing Volume. 

 

The two subnets Group 1 and Group 2 running IPv4 are interconnected via an IPv4 over IPv4 tunnel 

between Switch A and Switch B.
