3. Verify the configuration:

Use the display interface serial command to display information about Serial 2/0/1 of Router B.

The physical layer status and link layer status of the interface are both up, and the states of LCP and

IPCP are both Opened, indicating PPP negotiation is successful. Router A and Router B can ping

each other.
