Hi all. This will no doubt be very simple for someone - but I am quite new to this!
Essentially we have a server (server1) plugged into a C2950 - port 2. It has several addresses on one physical adapter. These are in different networks eg. 192.168.6.2, 192.168.7.2 etc . How can I get it to communicate with other servers on the same switch in these networks?
For example, server 2 and 3 with addresses 192.168.6.30 and 192.168.6.31 are plugged into ports 3 & 4 with static access VLAN 30. Server 4 and 5 with addresses 192.168.7.40 and 192.168.7.41 are plugged into ports 5 & 6 with static access VLAN 40.
If port 2 is configured as a static access in VLAN 30 it can communicate with servers 3 & 4. If port x2 is configured with static access in VLAN 40 it can communicate with servers 5 & 6.
I presumed making the port a trunk:
switchport trunk native vlan 30
switchport mode trunk
mls qos trust cos
macro description cisco-router
spanning-tree portfast trunk
spanning-tree bpduguard enable
would enable server 1 to communicate with all the others servers - but no joy (vlan 30 is the management vlan).
Any other suggestions? Obviusly if I used physical adapters on server 1 assigned them to the appropriate static access vlans then it would be fine.
I was trying to keep it simple to start with! - but its the inside address on an MS ISA firewall.
Initially a PIX sends the packets to the outside interface on the ISA (which is a trunk on the C2950 switch). That works fine.
The ISA forwards allowed traffic to the inside interface on the ISA (also on the same C2950). However, as mentioned, the inside address on the ISA has several address on different networks. These need to communicate with other servers in these networks on the same C2950. The config on c2950 on the port with the inside ISA interface is causing the problem somehow. I will leave it as a trunk and try putting VLANS on the server adapters.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
