have a brand new firewall and six 24 ports L3 capable HP switches ; existing network is small (<150 wks) ; currently running over L2 switches and little hubs !
Trying to get some good benefits from all these new equipments . so , my thought is like this :
Let's say we will have 2 VLANs : VLAN 1 and VLAN2
VLAN 1 : 10.10.1.0/24
VLAN 2: 10.10.2.0/24
Intra-VLAN routing should be enabled so that devices can talk to each other.
so , as far as I know , I have to create VLANs on the core switch ; dedicate interfaces to them and assign IP addresses on respective VLAN :
Interface GigaEthernet 0/1 / IP address :10.0.1.1/24
Interface GigaEthernet 0/2 / IP address :10.0.2.1/24
let's imagine IP routing is enabled on this switch . so these 2 VLANs can talk to each other . also ; probably I can define another interface and set static routs to send Internet traffic toward edge firewall.
Let's also imagine 5 other switches are connected (using 1 GB connections) and ports are
assigned to different VLANs, I think one GB trunking port should be considered on each of these five switches.
My dummy questions for now :
How physically I connect remaining 5 switches to core switch ? should I expect 5 trunk connections to core switch ? how interfaces on core switch will talk to trunk links ?
