Exterior Gateway Routing Protocols
2.2.2.2 is called a route reflector and is responsible for reflecting routes between its clients. Routes
received from the client 3.3.3.3 by the router 2.2.2.2 are reflected to 4.4.4.4 and vice-versa. Routes
received from 1.1.1.1 are reflected to all clients.
To configure router 1.1.1.1, use the following commands:
create vlan to_rr
configure vlan to_rr add port 1:1
configure vlan to_rr ipaddress 10.0.0.1/24
enable ipforwarding vlan to_rr
configure bgp router 1.1.1.1
configure bgp as-number 100
create bgp neighbor 10.0.0.2 remote-as 100
enable bgp
enable bgp neighbor all
To configure router 2.2.2.2, the route reflector, use the following commands:
create vlan to_nc
configure vlan to_nc add port 1:1
configure vlan to_nc ipaddress 10.0.0.2/24
enable ipforwarding vlan to_nc
create vlan to_c1
configure vlan to_c1 add port 1:2
configure vlan to_c1 ipaddress 20.0.0.2/24
enable ipforwarding vlan to_c1
create vlan to_c2
configure vlan to_c2 add port 1:2
configure vlan to_c2 ipaddress 30.0.0.2/24
enable ipforwarding vlan to_c2
configure bgp router 2.2.2.2
configure bgp as-number 100
create bgp neighbor 10.0.0.1 remote-as 100
create bgp neighbor 20.0.0.1 remote-as 100
create bgp neighbor 30.0.0.1 remote-as 100
configure bgp neighbor 20.0.0.1 route-reflector-client
configure bgp neighbor 30.0.0.1 route-reflector-client
enable bgp neighbor all
enable bgp
To configure router 3.3.3.3, use the following commands:
create vlan to_rr
configure vlan to_rr add port 1:1
configure vlan to_rr ipaddress 20.0.0.1/24
enable ipforwarding vlan to_rr
configure bgp router 3.3.3.3
configure bgp as-number 100
create bgp neighbor 20.0.0.2 remote-as 100
enable bgp neighbor all
enable bgp
