t permits spoke-to-spoke route advertisement using neighbor command. That's it. Let's look at this simple hub&spoke frame relay topology:                 s1   /  R2 R1-hub- -----------                   s2  / R3 with R1 being a hub (R2 and R3 don't have PVC between them). R1's DLCI 102 to R2 R1's DLCI 103 to R3 R2's DLCI 201 to R1 ... (more)

Routed Protocol : These are the protocols which help Routing Protocols to carry their information from one router to another example : ipv4 and ipv6. Routing Protocols : These Protocols are used to exchange routes dynamically ex. RIP , EIGRP , OSPF etc. These protocols are actually carried by Some of routed protocols. ex. EIGRP is a Layer - 3 protocol . So it uses IP protocol at layer 3 eit... (more)
