I'm might need some help to understand what would be the possible impact of DHCP snooping features configured on a 2960-L on IPv6 SLAAC configured on a 899-LTE.
Every time that I'm enabling the ip dhcp snooping vlan 100 on a 2960-L, my ipv6 hosts are not able to get an IPv6 address anymore.
After doing some packet captures I can see the host sending few RS messages but the router doesn't reply back with the any RA message.
If I remove the ip dhcp snooping vlan 100 from the 2960-L everything get's back to normal. The host will get an IPv6 via SLAAC and I can see the reply to the RS on the pcap.
What would be the link between the ip dhcp snooping and this? As far as I understood it should not have any impact or I'm wrong?
