Directions
" Configure the topology per the diagram
" Configure BGP on R1, R2, R3, R4, and R5 per the diagram
" R1 and R3 should use the private AS 65013 and the public AS 2
" R2 should use the private AS 65002 and the public AS 2
" R1 should peer with R3 and R4
" R2 should peer with R3 and R5
" Advertise R3’s Ethernet into BGP on R3
" Advertise VLAN 5 into BGP on R5
" Advertise VLAN 43 into BGP on R4
" Configure R1 to set VLAN 43 to the community Local-AS as it is received from
