DLCIs are locally significant

1) X.21
2) Frame Relay
3) ATM

How EIGP Handles NBMA (Non Bradcast Multicast Access)

EIGRP can use “pseudo-broadcasts” or manual neighbors*
Slipt horizon can be an issue
Disabled on Physical interfaces
Enable on sub-interfaces

* one manual neighbor disables EIGRP multicast

Frame Relay mapping Point to multipoint

Router 1

interface s0/0.1 multipoint
ip address
frame-relay map ip 102 broadcast
frame-relay map ip 103 broadcast (pseudo broadcast)


Ping – test reachability

Mapping neighbors manually

Slit Horizon

A router received an update will never foward it to the same interface
