The output information shows that Switch C has established an iBGP peer relationship with
Switch B.
3. Configure eBGP.
• The eBGP peers, Switch A and Switch B (usually belonging to different carriers), are
located in different ASs. Their loopback interfaces are not reachable to each other, so
directly connected interfaces are used for establishing BGP sessions.
• To enable Switch C to access the network 8.1.1.0/24 that is connected directly to Switch
A, add network 8.1.1.0/24 to the BGP routing table of Switch A.
# Configure Switch A.
