Yes, Rakib Bhai I've checked diagram. Since iBGP peering is up, so IGP and iBGP is working loop-free. So, issue is to/from outside. Could you check if next-hop-self is configured?

Dear Amin Vai,
If possible please see the network diagram it is denited my
requirement.I  dont check carefully the BGP table.However, my main
concern bgp through the L3 switch.BGP is running in Router and Caching
Control Server.L3 ensures inter vlan routing.We can ping from between
server,L3 and Router not outside network.
