Why does DHCP take a long time to issue an ip address to one client PC?

Question

Cisco

Hello everyone, there is a topology in ciso packet tracer in which there are 2 routers; 2 - switch; 2 - one of which is a client PC and DHCP is configured, but there is a problem: the client PC takes a long time to receive network settings via DHCP, why? there are no problems with the lack of addresses

Answer 1

Switches have STP enabled. The port does not forward frames until it enters the Forwarding state.
1. On switches globally:
spanning-tree mode rapid-pvst
2. On ports towards hosts:
spanning-tree portfast
spanning-tree bpduguard enable

Answer 2

Thank you!
