Yes, it is an internetworkexpert workbook (LAB 10). Cisco suggest this is
related to bug ID CSCds42715. I disabled fast switching (defaults to off on
2600) via the no ip route-cache command and it still does not work. I just
took the native vlan stuff off...my lab is in 8 weeks and I do not have the
time to play with it :o)

You can experience problems trunking on 10meg Ethernet interfaces when
using a native VLAN other than 1. Try removing the native VLAN or
changing the native VLAN to 1.
Also what workbook is this from? It looks like Internetwork Expert's
Lab 10 ;-)

Team,
In lab 10 router 4 has 2 Ethernet interfaces.. My 2600 series router has
only one interface so I am trunking 2 vlans to that routerss interface
by
creating sub interfaces with vlan tags etc. I can ping the switch's
interface vlan 100 from router 4 but I can not 204.12.1.254 (BB3) from
router 4. If I remove the native vlan tags everything works fine.
Evidently
there is a gap in my native vlan knowledge so will someone please lend a
hand to help me understand. If I figure it out before anyone responds
I'll
be sure to post my findings..
The I am having the following problem and perhaps it is a
misunderstanding
of the technology.
Router 4 has the following configuration
!
interface Ethernet0/0
no ip address
half-duplex
!
interface Ethernet0/0.43
encapsulation dot1Q 43 native
ip address 204.12.1.4 255.255.255.0
!
interface Ethernet0/0.100
encapsulation dot1Q 100
ip address 164.1.47.4 255.255.255.0
The 3550 has this configuration for router 4s uplink
!
Rack1SW1#show run int fa0/4
Building configuration...
Current configuration : 189 bytes
!
interface FastEthernet0/4
switchport trunk encapsulation dot1q
switchport trunk native vlan 43
switchport trunk allowed vlan 43,100
switchport mode trunk
switchport nonegotiate
end
