Afzaal,

First you need to check the following:

RouterA:

ip address 192.168.4.126 255.255.255.0

network 192.168.4.0 0.0.0.127

Although the Network statment is part of the interface Network, but to be precise you may correct it as follows:

IP address 192.168.4.126 255.255.255.128

RouterB:

ip address 192.168.4.254 255.255.255.0

network 192.168.4.128 0.0.0.127

Although the Network statment is part of the Network interface, but to be precise you may correct it to the following:

ip address 192.168.4.254 255.255.255.128

Second:

You need to disable (auto-summary), eithout disabling auto-summary, Eigrp Summarize the Network to its classfull Network at majour Network boundaries, so the routing table wont have the more Specific route for each Network.

The routing table in R1 will have the following Network:

192.168.2.0

192.168.3.0

192.168.4.0

Those Networks are being summarized due to the Auto-summary command. The correct solution is to disable auto-summary with (no auto-summary).
