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.
Regards
Rehman
