On SecPath C, establish an EBGP connection with SecPath A and an IBGP connection with
SecPath B; configure BGP to advertise network 9.1.1.0/24 to SecPath A, so that SecPath A can
access the intranet through SecPath C; configure a static route to interface loopback 0 on
SecPath B (or use another protocol like OSPF) to establish the IBGP connection.
