正解：
Solution Steps need to follow as below:
When we check on client 1 & Client 2 desktop we are not receiving DHCP address from R4 ipconfig ----Client will be receiving IP address 10.2.1.3
IP 10.2.1.3 will be able to ping from R4 , but cannot ping from R3, R2, R1
This clearly shows problem at R4 since EIGRP is between DSW1, DSW2 & R4 and OSPF protocol is running between R4, R3, R2, R1 so routes from R4 are not propagated to R3, R2, R1
Since R4 is able to ping 10.2.1.3 it means that routes are received in EIGRP & same needs to be advertised in OSPF to ping from R3, R2, R1.
Need to check the routes are being advertised properly or not in OSPF & EIGRP vice-versa.
From above snap shot it clearly indicates that redistribution done in EIGRP is having problem & by default all routes are denied from ospf to EIGRP... so need to change route-map name.
Change required: On R4, in redistribution of EIGRP routing protocol, we need to change name of route-map to resolve the issue...
So in ticket Answer to the fault condition will be as below for

Check for neighborship of ospf sh ip ospf nei ----- Only one neighborship is forming with R2 & i.e. with R3
Since R2 is connected to R1 & R3 with routing protocol ospf than there should be 2 neighbors seen but only one is seen
Need to check running config of R2 & R3 for interface Sh run -------------------------- Interface Serial0/0/0/0.12 on R2
Sh run -------------------------- Interface Serial0/0/0/0 on R1
- Change required: On R1, for IPV4 authentication of OSPF command is missing and required to configure------ ip ospf authentication message-digest
