Good evening, i just want to say thank you to all this amazing community you guys have been helping me a lot, i just made an account to ask my first question:
I have this topology in the attachment, and im trying to get the DHCP server to assign ip to the vlans, but i haven't been able to, im using OSPF to do the routing between the networks, im using VTP with the switches, the "Core" Switch is the server and the other ones are the clients, so far i can ping the R2 from the USER1 machine. R1 and R2 can ping each other, as well as the DHCP server, but i cant ping the R1 or the server from the vlans, what i have done:
1. Created the subinterfaces for the vlans in the R1 router 2 Assing the ip helper-address in the subinterfaces pointing to the DHCP server 3 Create the vlan pools in the DHCP server 4. Trunked the ports f0/1 and f0/3-6 in the Core switch 5. Create the vlans in the Core switch 6. Set the other switches as vtp clients with the same domain 7. Assign each vlan to its corresponding port in the vtp clients (with switchport acces vlan) 8. OSPF routing
On the VTP client side, enter the command ( sh vtp statistics ) and upload the result here please. I want to chick if there is any config digest error presents or not. Do it for all vtp client switchs.
Created the subinterfaces for the vlans in the R1 router ------- remove from R1 Assign the ip helper-address in the subinterfaces pointing to the DHCP server---- on core switch Create the vlan pools in the DHCP server Trunked the portsf0/1 and f0/3-6 in the Core switch Create the vlans in the Core switch Set the other switches as vtp clients with the same domain Assign each vlan to its corresponding port in the vtp clients (with switchport acces vlan) OSPF routing R1<->R2 <->core sw
1) All hosts to be set to dhcp
2) All access switch NOT to have ip routing enabled, Just acting as host switches with trunk interfaces connecting the the core switch
3) Core switch to HAVE ip routing enabled and trunk interfaces to the access switches L3 vlan interface for each of the subnets on the access switches On each L3 interface apply a helper address of the dhcp server Core switch to R2 subnet via ospf area 1 ( area 1 stub) Core switch advertising its L3 vlans subnets in ospf
4) R2 subnet to Core switch via ospf area 1 ( area 1 stub no-summary), with stub area (1) between core switch, the switch will be receiving default route from R2. R2 subnet to R1 via ospf area 0
5) Advertise ALL rtr 1 interfaces into ospf area 0
6) DHCP server - Same subnet of rtr - give this an ip address/subnet/ default –gateway pointing to rtr1
Should be good to go then.
Please don't forget to rate any posts that have been helpful.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
