The output shows two valid routes to destination 9.1.1.0/24. The route with next hop 3.1.1.1 is
marked with a greater-than sign (>), indicating it is the best route (because the ID of Switch B is
smaller). The route with next hop 3.1.2.1 is marked with an asterisk (*), indicating it is a valid
route, but not the best.
By using the display ip routing-table command, you can find only one route to 9.1.1.0/24 with
next hop 3.1.1.1 and outbound interface VLAN-interface 200.
3. Configure loading balancing:
Because Switch A has two routes to reach AS 65009, configuring load balancing over the two
BGP routes on Switch A can improve link usage.
# Configure Switch A.
[SwitchA] bgp 65008
[SwitchA-bgp] ipv4-family unicast
[SwitchA-bgp-ipv4] balance 2
[SwitchA-bgp-ipv4] quit
[SwitchA-bgp] quit
Verifying the configuration
# Display the BGP routing table on Switch A.
[SwitchA] display bgp routing-table ipv4
Total number of routes: 3
BGP local router ID is 1.1.1.1
