3. Perform the same operations on SecPath B and you can see that there is no P2MP GRE tunnel
established on SecPath B.
4. Cut off the tunnel link between SecPath A and SecPath C:
a. On SecPath C, select Device Management > Interface from the navigation tree and then click
the
icon of interface Tunnel0.
b. Click the Disable button to shut down interface Tunnel0.
5. After the tunnel aging time (10 seconds in this example) elapses, refresh and view the tunnel entry
information on SecPath A.
There should be no tunnel entry any more.
6. Ping Host A from Host C. The ping operation succeeds. Refresh and view the P2MP GRE tunnel
information on SecPath B again. You can see that a P2MP GRE tunnel is established on SecPath B,
as shown in
Figure 42 .

work, and after the timer expired, the tunnel entry on SecPath A was removed.
• After SecPath C sent a packet to SecPath B, a tunnel entry to the branch network was generated on
SecPath B, and packets to the branch network were forwarded through SecPath B
