4.2 Frame Relay & PPP over L2TPV3

R21 and R24 connect to the service provider by FR and PPP respectively.

configure L2TPV3 on R5 and R10 to support FR and PPP using interworking IP. Configure OSPF IPV4 on

the interfaces that are show in this table.

Ensure that R21 and R24 have full IPV4 connectivity.
