VLAN Multi-tagging
Hello guys can someone help me with my configuration I want to setup our ISP onto multi-tagging so that all on the VLAN can connect to the internet but they are not going to see each networks. Here's my config below:
hostname "HP-2920-24G" module 1 type j9726a timesync sntp sntp broadcast ip authorized-managers 192.168.2.15 255.255.255.0 access manager ip default-gateway 192.168.10.1 ip routing interface 1 name "Reserved" exit interface 2 name "Cable Link" exit interface 5 name "Servers" exit interface 6 name "Ldelupio" exit interface 13 name "Test Port" exit interface 24 name "CCTV" exit snmp-server community "public" unrestricted snmp-server contact " " oobm no ip address exit vlan 1 name "DEFAULT_VLAN" untagged 1-24,A1-A2,B1-B2 ip address 192.168.2.30 255.255.255.0 ipv6 enable ipv6 address autoconfig exit vlan 10 name "Admin" tagged 1-2 no ip address exit vlan 20 name "Tech" tagged 1-2,6 ip address 192.168.20.1 255.255.255.0 ipv6 enable ipv6 address autoconfig exit vlan 30 name "Opn" tagged 1 no ip address exit vlan 40 name "Lic" tagged 1 no ip address exit vlan 50 name "CCTV" ip address 192.168.0.10 255.255.255.0 ip address 192.168.10.10 255.255.255.0 ipv6 enable ipv6 address autoconfig forbid 1-2 exit vlan 60 name "Alert" tagged 2 no ip address exit vlan 100 name "Cablelink" no ip address exit primary-vlan 20 no autorun no dhcp config-file-update no dhcp image-file-update password manager password operator

Re: VLAN Multi-tagging
I am guessing that by "VLAN multitagging", what you mean is you want to trunk all your VLANs to your ISP.
If you want to do that, then you will have to remove all the VLAN interface IP addresses so your ISP can set them up as the router addresses for their respective VLANs.
All things considered, this is pretty much the opposite of my philosophy for network management (I want to control the Layer-3 interface for all my subnets and make my own routing decisions).
Also, I would be very surprised if your ISP agreed to do this for you.
If you don't want hosts in one VLAN accessing resources in another, you should use authentication and authorisation (ever since WindowsNT was released in 1993), not weird network topologies.
If you're really desperate, put some ACLs on the "core" switch, but ACLs don't really provide very good security.

Re: VLAN Multi-tagging
Yeah, just like your philosophy in network. I want to control my layer 3 to do the routing decision but they also need to have internet. Is my switch capable of DHCP function? I dont want them to locate my router. Can you help me with this configuration? Thanks.
