Hello! I'm trying to replace a Windows Server using a 2821 router.
INITIAL SITUATION
Server --- 2950 --- router
- Server: 10.0.6.230/24
- Router: 10.0.6.10/24
- The router interface can be pinged from the server
FINAL SITUATION
2821 --- 2950 --- router
- 2821 int vlan200: 10.0.6.230/24
- 2821 int fa1/15: no ip address, switchport access vlan 200
- Router: 10.0.6.10/24
- The router interface can't be pinged from the 2821
WHAT I HAVE SEEN DURING THE PROBLEM
The physical layer link to the switch seems ok.
I can see the 2950 switch with a "sh cdp neighbors"
I can see the router's mac in vlan200 with a "show arp"
I think the problem could be related to the 2950 arp or mac-address table but I can't access the 2950 nor the remote router.
Any idea of what is going on? Thanks!!

Hello, I don't manage the 2950 switch nor the remote router. I can only check the 2821 and I think everything is ok in my configuration.
This is the config in the 2821:
version 12.4
!
ip cef
!
interface GigabitEthernet0/0
ip address 192.168.0.1 255.255.255.0
!
interface FastEthernet1/15
switchport access vlan 200
!
interface GigabitEthernet1/0
switchport access vlan 100

Can you do an extended ping from the fa1/15 interface? For extended ping type ping on the command prompt. for Extended commands answer "y" and then give the source interface as FastEthernet1/15.example shown below. Please do tell us the result.

I will try the change again on monday so I will make this test then.
I'm thinking about sticky ARP in the 2950 would be likely to cause this problem... will let you know after monday.
Thanks
