GS,
i am trying to figure out what i am doing or missing here.
i am configuring dot1q between my R3 interface and my switch fa0/3. my R3 interface is connected to SW1 fa0/3 and R4 fa0/0 is connected to SW1 fa0/3. My R6 fa0/1 is connected to my SW2 fa0/6 i am trunking between SW1 and SW2.
Here is the problem:
When i configure encapsulation dot1Q 30 native under R3 and do the same thing under my SW1 switchport trunk native vlan 30 i can't ping but when i remove both configs i can ping.
There is no native vlan configured under R60/0.60 no problem pinging.
Here is my config :
SW1:
interface FastEthernet0/3
switchport trunk encapsulation dot1q
switchport trunk native vlan 30
switchport mode trunk
switchport nonegotiate
duplex full
!
interface FastEthernet0/4
switchport access vlan 30
switchport mode access
duplex full
R3:
interface Ethernet0/0.30
encapsulation dot1Q 30 native
ip address 10.80.80.3 255.255.255.0
!
interface Ethernet0/0.60
encapsulation dot1Q 60
ip address 10.80.90.3 255.255.255.0
