Looked over the documentation and most of the DHCP snooping posts here, but have yet to see a scenario such as the one that I'm getting ready to roll outâ¦wanna get it correct the 1st time.
Here's what it looks likeâ¦
â¢Hub / Spoke topology
â¢Hub and Spoke tied together w/ Gigaman and EIGRP (not extending VLAN's over WAN)
â¢Gigaman is hooked into a 6500 at the hub location w/ the DHCP servers hanging off of it - directly connected
â¢Spoke rails will get DHCP from Hub
â¢DHCP snooping is NOT configured at hub or spoke today
â¢Want to enable snooping at spoke
spoke-switch (config)# ip dhcp snooping
spoke-switch (config)# ip dhcp snooping vlan x
spoke-switch (config)# ip dhcp snooping information option
spoke-switch (config-if)# ip dhcp snooping trust ïL2 trunk or DHCP server port
1.)I saw a post that mentioned not using the command 'ip dhcp snooping information option' if I use Windows 2003 DHCP server. Is this correct?
2.)Do I need to configure 'ip dhcp snooping trust' over the /30 access port between the HUB and Spoke?
3.)Do I need to configure anything related to DHCP snooping at the hub? I will be dragging this Gigaman WAN connection into a 6500 - the same 6500 that the DHCP server is connected to.
