I have 3 switches in a triangle running EAPS. Each switch has vlan(s) that are only local to that device. IE;

Switch 1:
Vlan A

Switch 2:
Vlan B,C

Switch 3:
Vlan D,E

Also, there are some VLans that are common between those switches. I currently have those vlans added to the "Lags" between each switch, and I have them added to my EAPS domain.

My question,

I want Switch 1,3 to know about the network on switch 2 and vise versa.

I ran these commands on Switch 2;
enable ipforwarding
enable rip
configure rip add vlan all

Now my question, how do I get switch2 to send its networks across the LAG without tagging the VLAN on the LAG? Right now, on switch 2, if I tag VLANS B,C on the LAG.. then the other switches route tables will show the networks. If I dont tag B,C then the other switches dont know about the networks.

I dont want B,C to be added as a VLAN to any other switch, but I want the other switches to know about it.

Thanks!

Here is a brief layout of the devices..

So there is L3 connectivity between all 3 switches. I enabled IPforwarding on all vlans on all switches, as well as RIP.

I'm not seeing the vlans local to each switch being propogated via RIP.

Also; will that cause problems for me if one end of the LAG there is added VLANS tagged, but its not reflected on the other end?

IE;
SW1 (Tag A,F,G,H) <---LAG---> SW2 (Tag B,C,F,G,H)
