Ensure that when pinging to destination 10.80.80.255 from R3 that R1, R6, R8, and Switch1 reply.
R7 used to belong to VLAN4 but has been moved to VLAN5 and is now unreachable; configure the network in such a way that communication can still exist between VLAN4 and just the Ethernet address of R7 without modifying the IP address of R7.
Allow R7 to ping the IP addresses assigned to Loopback0 on R1, R4, R5, R6, and R8 do not assign any static, dynamic, or policy routes to achieve this. Perform config-uration only on R7.
Configure R4 so that if R1 and R6 both advertised VLAN2 within OSPF in the future that R4 would be able to load share to this destination across both Frame Relay PVCs; do not change the bandwidth statements on your PVCs.
