Yes, I guess that information might be helpful.

I'm ping from R2 (204.12.1.2) on the same ethernet segment to
R6(204.12.1.6) There is also BB3(204.12.1.254) on the same segment which I
can ping to just fine from R2. I can't ping to or from R6 unless I remove
the subinterfaces and put the IP address on the physical interface and just
make the switch port an access port in Vlan 263 (same as R2)

I'm having some problems getting this configuration to work. I can't figure
out why on a debug ip packet detail, when I ping to or from this I get
encapsulation failed. When I delete the subinterfaces and assign the IP
address to the physical interface and put the switchport in vlan 263, it is
successful. After staring at my configuration for an hour , I can't see
anything wrong with it. Can someone verify this?

Switch1:
interface FastEthernet0/6
 switchport trunk encapsulation dot1q
 switchport trunk native vlan 263
 switchport mode trunk

R6:
interface Ethernet0/0
 no ip address
 half-duplex
!
interface Ethernet0/0.6
 encapsulation dot1Q 6
 ip address 163.1.6.6 255.255.255.0
 no cdp enable
!
interface Ethernet0/0.263
 encapsulation dot1Q 263 native
 ip address 204.12.1.6 255.255.255.0
 no cdp enable

Thanks in advance,
Bill
