Configuration Roadmap
The configuration roadmap is as follows:
1. Set up EBGP peer relationships between SwitchA and SwitchB, and between SwitchA and
SwitchC. Create an IBGP peer relationship between SwitchB and SwitchC.
2. Configure load balancing and the MED on SwitchA and check the routing table.
Data Preparation
To complete the configuration, you need the following data:
l The VLAN ID of each interface is shown in Figure 7-7.
l The IP address of each VLANIF interface is shown in Figure 7-7.
l The router IDs of SwitchA is 1.1.1.1, the number of the AS where it resides is 65008, and
the number of routes for load balancing is 2.
l The router IDs of SwitchB and SwitchC are 2.2.2.2 and 3.3.3.3, the number of the AS where
they reside is 65008, the default MED of SwitchB is 100.
Configuration Procedure
1. Create a VLAN to which each interface belongs.
The configuration details are not mentioned here.
