> Hello
>
> Here's the thing.
> R6 is connected to Fa0/11on SW2 in my lab and
> R7 is connected to Fa0/18 on SW2 in my lab
> At first I'm able to see SW2 when I type "sh cdp neig" on my routers.
> Then when I add the command "switchport access vlan 2567" on Sw2's
> Fa0/11 and Fa0/18, SW2 is "removed" from the cdp neighbor table on
> router 6 and 7.
>
> The output is further down:
> 1. R6 can see the see the SW2
> 2. R7 can see the SW2
> 3. Here is the config on SW2 ( I just have the interface config here,
> the ports are: speed 10, half-duplex )
> 4. Here is config on R6
> 5. sh ip arp for R6
> 6. Here is config for R7.
> 7. sh ip arp for R7
> QUESTION: why are R6 and R7 not able to see each others ip addresses
> int the "arp table"?
> MY GUESS: because "switchport access vlan 2567" has not been configure
> on SW2 yet ( like in proctor guide page 15 )
> But here's the thing when I add that to SW2's Fa0/11 and Fa0/18, R6
> and R7 "loses" SW2 in the cdp neighbor" -table
>
> 8. I add "switchport access vlan 2567" to SW2's Fa0/11 and Fa0/18
> 9. About a minute after, this is displayed in "sh cdp neigh" on R6, R7
> and SW2
> As one can see none of the devices are able to see eachother in the
> "sh cdp neigh- table"
>
> What could be causing this?
> What do I have to do, to solve this? I want ping to work between R6
> and R7.
