Video 6: Implementing Advanced EIGRP

DLCIs are locally significant

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

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 172.16.124.1 255.255.255.248
frame-relay map ip 172.16.124.2 102 broadcast
frame-relay map ip 172.16.124.3 103 broadcast (pseudo broadcast)

Verify

Ping – test reachability

Mapping neighbors manually

router eigrp 25

neighbor 10.10.10.10

Slit Horizon

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