Exterior Gateway Routing Protocols
between sub-AS 65001 and sub-AS 65002. Router B and router D are EBGP peers. EBGP is also used
between the confederation and outside ASs.
To configure router A, use the following commands:
create vlan ab
configure vlan ab add port 1
configure vlan ab ipaddress 192.1.1.6/30
enable ipforwarding vlan ab
configure ospf add vlan ab area 0.0.0.0
create vlan ac
configure vlan ac add port 2
configure vlan ac ipaddress 192.1.1.17/30
enable ipforwarding vlan ac
configure ospf add vlan ac area 0.0.0.0
enable ospf
configure bgp as-number 65001
configure bgp routerid 192.1.1.17
configure bgp confederation-id 200
enable bgp
create bgp neighbor 192.1.1.5 remote-AS-number 65001
create bgp neighbor 192.1.1.18 remote-AS-number 65001
enable bgp neighbor all
To configure router B, use the following commands:
create vlan ba
configure vlan ba add port 1
configure vlan ba ipaddress 192.1.1.5/30
enable ipforwarding vlan ba
configure ospf add vlan ba area 0.0.0.0
create vlan bc
configure vlan bc add port 2
configure vlan bc ipaddress 192.1.1.22/30
enable ipforwarding vlan bc
configure ospf add vlan bc area 0.0.0.0
create vlan bd
configure vlan bd add port 3
configure vlan bd ipaddress 192.1.1.9/30
enable ipforwarding vlan bd
configure ospf add vlan bd area 0.0.0.0
enable ospf
configure bgp as-number 65001
configure bgp routerid 192.1.1.22
configure bgp confederation-id 200
enable bgp
create bgp neighbor 192.1.1.6 remote-AS-number 65001
create bgp neighbor 192.1.1.21 remote-AS-number 65001
create bgp neighbor 192.1.1.10 remote-AS-number 65002
