hosts on R3’s Ethernet have access to VLAN 5 and VLAN 43 but hosts on
VLANs 5 and 43 do not have access to each other
Directions
" Configure the topology per the diagram
" Configure EIGRP AS 2 on the links between R1 & R3 and R2 & R3
" Configure BGP on R1, R2, R3, R4, and R5 per the diagram
" R1 should peer with R4
" R2 should peer with R5
" R1, R2, and R3 should all peer with each other
" Advertise R3’s Ethernet into BGP on R3
" Advertise VLAN 5 into BGP on R5
" Advertise VLAN 43 into BGP on R4
" Configure an AS-Path access-list on R1 and R2 to only advertise routes
originated in AS 2 out to AS 1 and AS 3
