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.
# Configure Switch B.
[SwitchB] bgp 65009
[SwitchB-bgp] import-route direct
# Display the BGP routing table on Switch A.
[SwitchA] display bgp routing-table
Total Number of Routes: 4
BGP Local router ID is 1.1.1.1
Status codes: * - valid, ^ - VPNv4 best, > - best, d - damped,
h - history, i - internal, s - suppressed, S - Stale
Origin : i - IGP, e - EGP, ? – incomplete
Network NextHop MED LocPrf PrefVal Path/Ogn
*> 2.2.2.2/32 3.1.1.1 0 0 65009?
* 3.1.1.0/24 3.1.1.1 0 0 65009?
*> 8.1.1.0/24 0.0.0.0 0 0 i
*> 9.1.1.0/24 3.1.1.1 0 0 65009?
Two routes 2.2.2.2/32 and 9.1.1.0/24 have been added in Switch A’s routing table.
# Display the BGP routing table on Switch C.
[SwitchC] display bgp routing-table
Total Number of Routes: 4
BGP Local router ID is 3.3.3.3
Status codes: * - valid, ^ - VPNv4 best, > - best, d - damped,
h - history, i - internal, s - suppressed, S - Stale
Origin : i - IGP, e - EGP, ? - incomplete
Network NextHop MED LocPrf PrefVal Path/Ogn
i 2.2.2.2/32 2.2.2.2 0 100 0 ?

* i 9.1.1.0/24 2.2.2.2 0 100 0 ?
You can find the route 8.1.1.0 becomes valid with the next hop as Switch A.
