The output shows that Switch B has established an iBGP peer relationship with Switch C and an eBGP
peer relationship with Switch A.

From the above outputs, you can find Switch A has learned no route to AS65009, and Switch C has
learned network 8.1.1.0 but the next hop 3.1.1.2 is unreachable, so the route is invalid.
4) Redistribute direct routes
Configure BGP to redistribute direct routes on Switch B, so that Switch A can obtain the route to
9.1.1.0/24 and Switch C can obtain the route to 3.1.1.0/24.
