Good afternoon all.
This may be a stupid question, hence the reason I'm not getting anywhere.
I have 3 switches.
1 Core and 2 connected to the main switch
So Core 6248 has a LAG Port and Physical Connection to Slave one. and Slave 2. for purpose of question.
We have VLAN 1 and 20 on all three switches and The LAG Ports are set as General with VLAN 1, & 20 Allowed.
We have an IP address assigned to one of the slave switches on VLAN20 in the 172.16.20.x Range and routing is enabled as follows.
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
S 0.0.0.0/0 [1/0] via 192.168.0.248, vlan 1
C 172.16.20.0/22 [0/1] directly connected, vlan 20 - Phone Network
C 192.168.0.0/22 [0/1] directly connected, vlan 1 - Core Network for Gateway and servers etc
This is owing to the fact the switch has ip phones attached to it, and pcs running via those phones, this routing allows the phones to talk to each other, and for the pc's to traverse the network, and get out to the default gateway for internet and service etc.
We now would like to add a phone to the second slave switch, that only has routing on the vlan1, but I can not see an easy way to get the VLAN 20 traffic to route, as if I assign a 172.16.20.x IP address to the VLAN interface it gets confused, as the routing is all wrong.
Current IP Route for Slave 2
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
S 0.0.0.0/0 [1/0] via 192.168.0.248, vlan 1
C 192.168.0.0/22 [0/1] directly connected, vlan 1
There is no VLAN routing setup on the Core (Main switch) other than the following route.
Route Codes: R - RIP Derived, O - OSPF Derived, C - Connected, S - Static
B - BGP Derived, IA - OSPF Inter Area
E1 - OSPF External Type 1, E2 - OSPF External Type 2
N1 - OSPF NSSA External Type 1, N2 - OSPF NSSA External Type 2
S 0.0.0.0/0 [1/0] via 192.168.0.248, vlan 1
C 192.168.0.0/22 [0/1] directly connected, vlan 1
what am I doing wrong. Many thanks in advance.
Because of the routing as configured, on Slave I can ping IP Device on Slave 2 but not on VLAN20, so the phones will not work.
