I don't see the point in all those static routes, apart from the default.
The 2948G-L3 is capable of routing and switching, and should be used as
such. I expect to see the subinterfaces (with the appropriate VLANs) on your
trunk ports only. The access ports should only have the relevant
bridge-groups assigned to them. Lastly, you need to enable routing for the
remaining bridge-groups - 20, 30, and 40. This is how I would configure your
2948G-L3:
bridge irb
int f1 through to f40
bridge-group 10
int f41 through to f42
bridge-group 20
int f43 through to f44
bridge-group 30
int g50
no ip add
int g50.10
encaps dot1q 10
bridge-group 10
int g50.20
encaps dot1q 20
bridge-group 20
.
.
int bvi 10
ip add 10.1.1.10 255.255.0.0
int bvi 20
ip add 10.2.1.1 255.255.0.0
int bvi 30
ip add 10.3.1.1 255.255.0.0
bridge 10 protocol ieee
bridge 10 route ip
bridge 20 protocol ieee
bridge 20 route ip
bridge 30 protocol ieee
bridge 30 route ip
bridge 40 protocol ieee
bridge 40 route ip
end
