I have core Switch 6506 series at HO location, OSPF applied on the Switch to advertise all networks to remote routers locations which ospf applied as well on all routers that has VSIs.
Now, in between, I mean between HO switch to all routers at remote locations, I have 2950 switch, which carries the vlan traffic from/to each others.
I have assigned the port f0/23 on 2950 switch which connected to port 2/23 6506 switch as trunk port as well as 6500 port 2/23 and allows the configured vlans.
the remote routers has (SVI) and configured as:
(conf)int vlan x
ip address x.x.x.x x.x.x.x
(conf)int vlan y
ip address y.y.y.y y.y.y.y
(conf) router ospf (process id)
network x.x.x.x (etc)
network y.y.y.y (etc)
the same likely Scenario apllied on 6500 series.
Now, my concern about the 2950 Switch in between, the trunk between 2950 to 6500 is configured to allow native vlan x, it works fine, but if I remove the Native Vlan & configure the port to allow the same vlan as tagged vlan i.e: switchport trunk allow vlan x, then the traffic is discarded, As I noticed i can't pass more than one native vlan through a trunk, and we might need multiple vlans to be carried out for multiple links.
Now, my question is How would I let specific Vlans tagged to be be passed from 6500 till it reaches their remote locations without usin the Native Vlan (Number) config on both Switches.
Appreciate ur feedback & help, since this problem puzzled me a lot.
