VLAN Interface vs VLAN - Find out the difference, now!

A rose by any other name.... That is how I feel about the VLAN Interface. It isn't the VLAN itself, and it can be called a Management Interface, a Switched Virtual Interface (SVI), or a VLAN Interface. I you are wondering about a VLAN vs an Interface VLAN, this short video is for you !!!

hey Keith, thanks for upload.

Can you explain how you managed to ping between vlans ?

I've setup ip routing on 3560, can see routes in routing table but yet both of my host not seeing routes or ping each other...

another question - does SVI interface needs to be added to vlan ?

@d3f4c3d

Thanks for the comments. The multilayer switch will have 2 VLANs, and have an SVI for each VLAN. The SVIs will be assigned IP addresses from 2 different subnets (which match the subnets, one for one, that the PCs are connected to. Each of the PC's needs to point to the SVI as their default gateway. On the 3560, you need to issue the global command "ip routing". The VLANs would need to exist as well.

I have over 40 on my youtube channel: Keith6783

Nova Datacom, the company I work with, has full training offerings for ICND1, ICND2, and Network Plus as well that I have recorded, but those are not up on youtube.

Thanks for the kind words,

Thanks. I am always willing to learn new things. I blame it on too much V-8 juice and a wife that wont let me have fun. But, I didnt know about fall back bridging. Spoke too soon. Thank you again.

[d3f4c3d]

@2007Russdog You can communication between Vlans, that could be accomplished with fallback bridging.

[2007Russdog]

@d3f4c3d Router are only needed for routing to different vlans if you dont have a layer 3 switch. Otherwise, you can use subinterfaces on the router as the vlans default gateway. If you dont use either IP routing or subinterfaces, you cant communicate between vlans

Goooooood explanation . good luck bro

[AdnaneLondon]

man ... you are good ,,, even the way you talk and the way you explain is just perfect ,, i thank you ...

[d3f4c3d]

@d3f4c3d first question was solved - for some reason my hosts that are routers were not setup with default gateways, i had to setup default routes to SVI of the switch to get that going...

And i guess SVI interface cant be added to vlan because its acting more like trunk port and not switchport ?

correct me if im wrong, thanks !

Keith6783,

Great video and simplified explanation of something many Sr. Engineers have trouble explaining to newbies to networking. Thumbs up from me!
