Single VLAN existing on Multipule interfaces?
-
Ok so heres the scoop.
I have 2 Cisco 2950's (i know old, please don't laugh. They were free and they work :)) I have all my VLANs configured on both switches [7,10,11,37,100]. I also have these VLANs defined on my PFSense router (Stephew10 FTW on my firebox]. I have this setup working fine with one switch and a single 2 port LAGG.
I'd like to take my second switch, setup a second LAGG on the router, then also have all of my VLANs exists on both interfaces so that all VLANs can be accessed and used on both switches.
I've done a bit of research, but I cannot find if anyone has even done something like this… Is this even possible?
Thanks,

Use switch trunk ports to trunk VLANs between switches, not router ports.

I know i can get a working configuration, with all my VLans existing on all switches, by doing the following:
Router - msk2,msk3 - LACP Lagged Trunk
|
|–- Switch 1 [Ports 23/24 Connected to msk2,msk3 on the router, and ports 21/22 to extend the LAGG to another switch]
|
|–- Switch 2 [Ports 23/24 connected to 21/22 on switch 1]However the configuration I'm looking for is as follows:
Router [msk0.msk1 - LAGG1] [msk2,msk3 - LAGG0] both LACP Trunks
| |
|–- Switch 1 |--- Switch 2And still have my Vlans exist on both switches....
Or can I create a single 4 port LAGG [msk0-3] and connect 2 ports of the LAGG to each switch? ie:
Router [msk0-3] LACP LAGG
| |
| |–-Switch 2 [ports 23/24 connected to msk2/3]
|–-Switch 1 [ports 23/24 connected to msk0/1]or am what I am asking simply impossible?

Router [msk0.msk1 - LAGG1] [msk2,msk3 - LAGG0] both LACP Trunks

|–- Switch 1 |--- Switch 2Why on Earth would you want to do that? Use a switch.

A router is not a switch. Bridging interfaces tries to make it a switch but never succeeds.
This has been discussed in all possible (and quite some impossible) configurations already.
