Step 3 Verify the configuration.
After the configuration is completed, executing the display interface command on every
switch, you can see the LCP status is Opened.
Take Switch A as an example.

NOTE
l When you configure an IP address for an interface on a PPP link, if you delete the IP address of the
interface on the PPP link that fulfills the IPCP negotiation and assign this IP address to an interface on
another PPP link, the IPCP negotiation of the later PPP link is definitely unsuccessful. To solve this
problem, you can run the shutdown and undo shutdown commands on the former interface to restore
the IPCP negotiation or assign a new IP address to the later interface.
l When you configure an IP address for an interface on a PPP link, if the configuration is correct but the
negotiation is always unsuccessful, it is recommended that you assign a new IP address to the interface.
