*>i 8.1.1.0/24 0 0 65008i
NOTE:
From the above outputs, you see that Switch A has not learned a route to AS 65009, 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.
14.
Redistribute connected routes.
15.
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.
