Hi,
I am confused in routing
I have 5 6500 switches (4 are core devices and 5th is used for WAN).It is collapsed core design.
Each core switch has a common 2 common vlans which are access ports (vlan31 and 25). ospf is used as RP with area 0 only
I have a 3750 (layer 2) switch hanging off core swich 4. A trunk connection is running between the two.
core switch 4 does not have vlan 20. it only has a route 192.168.20.1 (vlan20 ) thru switch 5 as vlan 20 sits on switch 5.
My question is if i create vlan 20 on 3750 switch and include in the trunk to core 4 (no vlan 20 on core 4) , will vlan 20 be routable thru switch core 4. core 4 only has a route to vlan 20 thru connected switch 5.
How can this be achieved.
Please Advice
