We are in process to implement the DHCP snooping in to our network (multiple buildings)and
all the location, Users of all the locations are getting the ip address from DHCP except
We have one location which has got 50 users and all the users nodes are taking the DHCP Ip
address from different building over WAN (with help of IP helper-address), but after DHCP
snooping implementation users are facing difficulty on this, even all the trunk interface
ports are trusted for DHCP snooping. Please find the connectivity scenario with location A
|||||A-DHCP User-->A-user access switch-->A-Core switch-->WAN ATM
network-->B-Core Switch-->B-Server access Switch-->B-DHCP server
Please help on this and have look in to some technical detail:
#A- user VLAN: Vlan ID 31
#B- Server VLAN: Vlan ID 40
# All the switches are in to transparent mode.
# all the switch between A & B is having DHCP config and trunk interface are trusted.
