You cannot use the same switch port as reflector port which is being used as trunk.
A reflector port SHOULD be an unused port on the switch.

Subject: RSPAN makes trunk go down

Hi,

I am trying to configure the lab RSPAN of IE vol1 part 1 page 163.

Before configuring RSPAN, the trunk works :

    ccieSW1(config)#do sh int tru
    Port Mode Encapsulation Status Native
 vlan
    Fa0/13 desirable n-isl trunking 1

But as soon as I type the command "monitor session 1 destination remote
 
vlan 100 reflector-port FA0/13" on SW1
the "show int trunk" becomes empty : no trunk anymore.

Does anybody have a clue why it goes down ?

Thanks,
Navid
