Will it be any problem if i add in the vlan interface in all the 3000 series switches? Any advantage or disadvantage of doing that?
If only one L3 switch is doing the routing, then what's the purpose of using L3 3000 series switches for most or all of their switches?
Does that mean that i can either add an IP in my physical switch's interface that's connected to the Router + One static route to the router interface connected to the L3 switch?(IP not in the configured vlan)
Use 2 IP of the vlan created in the L3 switch for the serial link?
For this case, must the router connect to the L3 switch or any L2 switch?
What if i;ve different vlan on different L3 switches? (eg. vlan 10-20 on L3 Switch 1 and vlan 30-40 on L3 switch 2). Will the vlan between these 2 switches be able to talk to each other without using a router?
Besides HSRP, what's the other reason of using full L3 switches in a network? for HSRP normall, i will only need 2 right?(1 active one standby).
If you have different vlans on the L3 switches and you dont have a common vlan database across the network, then you have to do intervlan routing on each and every L3 switch which have different vlans. Taking you example:
On switch1, you will do inter-vlan routing for vlans 10-20 by creating the "interface vlan XXX" Layer-3 SVI for each vlan.
On switch2, you will do the same for vlan 30-40. Now, to have a communication between the switch1 and switch2 networks, you hhave to use either static routes or a routing protocol like RIP.
Depending your network design you can have multiple advantages of using a Layer3 switch. For example it can act as a router for a small network.You can have it as a distribution for a building where you will do inter-vlan routing for your vlans and have Layer-3 link to your core switch.
You need a routing protocl when you need to do routing between the switches. For example Switch1 with Vlan 10-20 and switch2 with vlans 30-40, then you need a routing protocol to have routing done between these two switches.
If you have a standalone switch with multiple vlans, you dont need a routing protocol on it. You can simply configure the L3 SVI interface to configure the inter-vlan routing on it.
