After the configuration, the status of tunnel interfaces goes Up, and the tunnel interfaces can
ping each other successfully.
Take Router A as an example:
[RouterA] ping -a 40.1.1.1 40.1.1.2
PING 40.1.1.2: 56 data bytes, press CTRL_C to break
Reply from 40.1.1.2: bytes=56 Sequence=1 ttl=255 time=24 ms
Reply from 40.1.1.2: bytes=56 Sequence=2 ttl=255 time=33 ms
Reply from 40.1.1.2: bytes=56 Sequence=3 ttl=255 time=48 ms
Reply from 40.1.1.2: bytes=56 Sequence=4 ttl=255 time=33 ms
Reply from 40.1.1.2: bytes=56 Sequence=5 ttl=255 time=36 ms
--- 40.1.1.2 ping statistics ---
5 packet(s) transmitted
5 packet(s) received
0.00% packet loss
round-trip min/avg/max = 24/34/48 ms
Step 4 Configure a static route.
# Configure Router A.
[RouterA] ip route-static 10.2.1.0 24 tunnel 0/0/1
# Configure Router C.
[RouterC] ip route-static 10.1.1.0 24 tunnel 0/0/1
After the configuration, run the displayip routing-table command on Router A and Router C.
You can find the static route to the network segment of the remote user end through the tunnel
interface.
Take Router A as an example:
[RouterA] display ip routing-table
Route Flags: R - relay, D - download to fib
