LAB: PPP over Frame Relay

Requirements:  no router may use subinterface

bandwidth  64

int s0/1/0

encapsulation frame-relay

no frame-relay inverse-arp

frame-relay interface-dlci 602 ppp virtual-template 1

note:
- virtual access interface nos. issuing shut/no shut it will not assume always the same nos of virtual access interface.
- show ip route - will show /32 for virtual access. so might create problem on some dynamic routing.

verification
show int virtual access 2 - information inherited shows 100M link from virtual template
need to update the BW at virtual template

==============================================
100.100.120.0/24 128K 2 pvcs are active using 64k
note: there will be no load sharing / you can use multilink.

encapsulation frame-relay

no frame-relay inverse-arp

frame-relay interface-dlci 412 ppp virtual-template 3

frame-relay interface-dlci 422 ppp virtual-template 3

verification:

show ip route - there will one single set of /32 virutal access #
show int virtual-access # - will show only inherited 64k from virtual-template
show ppp multilink  - will show 2 member w total of 128K (definitive answer)
