Can anyone point me in the right direction with this question?
If you have two switches, with a router in the middle, connected via ethernet on both sides, if i'm using inter VLAN routing, do i need subinterfaces for each VLAN on the router? For example,
Fa0/0 on router is trunked and has .1,.2,.3,.4 for VLAN's 2,3,4 with subinterfaces all on /25, works fine.
Fa0/1 on same router connected to other switch, wanting to connect VLAN's 2,3,4 (also configured on 2nd switch) but can't seem to use /25 for sub's on Fa0/1 as overlaps with Fa0/0, does there even need to be more sub's on Fa0/1 or should they be connecting to 1st set of sub's on Fa0/0?
Sorry if this sounds a bit vague guy's hope someone can help
