Two core layer 3 switches were configured with HSRP.R1 is active and R2 is standby.There is a external DHCP server connected on R1 and R2.
I enabled the dhcp snooping and IP help-address on each core switches.I could find the DHCP snooping binding table on R1 after clinets got IPs, not on R2.
Now I want to enable IPSG and DAI feature.
If R1 goes down off,R2 will take over.
I think R2 will block traffic because no dhcp snooping binding table on R2.
Therefore When R1 have DHCP snooping binding table, how to synchronize the R2?or otherwise solution?
Thanks a lot!
