to gain reachability between R3’s Ethernet segment and VLAN 5
Directions
" Configure the topology per the diagram
" Configure EIGRP AS 1 between R4 and R5
" Configure EIGRP AS 2 between R1 and R3
" Configure BGP on R1, R3, R4, and R5 per the diagram
" R1 should peer with R3 and R4
" R4 should peer with R5
" Advertise R3’s Ethernet segment into BGP
" Advertise R5’s Ethernet segment into BGP
" Configure redistribution on R1 and R4 to allow IGP next-hop lookup in order to
gain reachability between R3’s Ethernet segment and VLAN 5
