I still don't understand the issue.

Which feature of the dynamic access is causing the problem ?

Thank you

You have your switch interface ports that R1, R2, R6, and BB2 connect to set
to dynamic. The "show isdn status" command will show these ports as going
between a trunk and access port. Set them to access mode with the
"switchport mode access" command and this should solve the issue.

Internetwork Expert Lab 16 - Task 2.5 - 2.7

I think have an issue with STP:

R1 - E0/0 connected to SW1-Fa0/1 (VLAN16)
R2 - E0/0 connected to SW1-Fa0/2 (VLAN22)

Also, by using trunking:
 R6 - Fa1/0.16 <-> SW1- Fa0/6 (VLAN 16)
 
And
BB2 - <-> SW1- Fa0/24 (VLAN 22)

As soon as the bridge comes up over the FR link, you cannot ping R6 from
R1
and BB1 from R2 (and vice-versa).

I have looked at the STP status and SW1's FastEthernet ports connected to R1
and R2 are in blocking mode....

Did anybody experience something similar ?

Thank you

Narcis
