TSHOOT : EIGRP over NBMA




 In the above practical, I wanted to revise whatever I learned in CCNP route EIGRP:

Above diagram is in the GNS3 and to the right in the logical diagram of the network.

I covered following eigrp over
1> multipoint NBMA
2> point to point NBMA
3> point to multipoint
4> redistribution

I am going to paste the config of the R1 and R5. And outout from R7 and R4

Why split horizon is required on serial0/0 on R1 and R5??
