Is there way to create a vlan interface that wouldn't be routed, like on a layer 2 switch ?
I'd like to use this interface on a layer 2 isolated network, only to managed the c3750 by ssh.
sorry, I wasn't clear about the deploment :
I have a c3750 stack with 10vlans and 8 interfaces vlan :
Vlan1 10.114.253.254 YES NVRAM up up
Vlan2 10.114.1.254 YES NVRAM up up
Vlan10 10.114.10.254 YES NVRAM up up
Vlan11 10.114.11.254 YES NVRAM up up
Vlan12 10.114.12.254 YES NVRAM up up
Vlan249 10.114.249.254 YES NVRAM up down
Vlan250 10.114.250.254 YES NVRAM up up
Vlan252 10.114.252.254 YES NVRAM up down
with the "ip routing" activated
So there's a route created automatically for the vlan interfaces/subnet :
10.0.0.0/24 is subnetted, 6 subnets
C 10.114.10.0 is directly connected, Vlan10
C 10.114.11.0 is directly connected, Vlan11
C 10.114.12.0 is directly connected, Vlan12
C 10.114.1.0 is directly connected, Vlan2
C 10.114.250.0 is directly connected, Vlan250
C 10.114.253.0 is directly connected, Vlan1
S* 0.0.0.0/0 [1/0] via 10.114.250.1
I'd like to create an interface vlan 254 with an ip address that would not appear in the routing table.
I don't want the subnet of vlan 254 to be routed by the c3750 stack.
The global routing table will contain all the routes. If you want to have a separate routing table for your management only, then you need to create a VRF and put your management vlan in that VRF. This way you have complete separations between global and VRF tables.
