I have a 3750x Stack where intervlan routing appears to be partally broken. IP Routing is enabled.
Version:
Cisco IOS Software, C3750E Software (C3750E-UNIVERSALK9-M), Version 15.2(4)E1, RELEASE SOFTWARE (fc2)
The Two VLANs:
FWC-Hen-Swi-Core# show run int vlan 1
Building configuration...
Current configuration : 58 bytes
!
interface Vlan1
ip address 10.10.40.0 255.255.0.0
end
FWC-Hen-Swi-Core# show run int vlan 15
Building configuration...
Current configuration : 59 bytes
!
interface Vlan15
ip address 10.15.40.1 255.255.0.0
end
Ping results VLAN 1:
FWC-Hen-Swi-Core#ping 10.10.80.20 source vlan 1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.10.80.20, timeout is 2 seconds:

Routing table:
Gateway of last resort is 10.10.30.2 to network 0.0.0.0
S* 0.0.0.0/0 [1/0] via 10.10.30.2
10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C 10.10.0.0/16 is directly connected, Vlan1
L 10.10.40.0/32 is directly connected, Vlan1
C 10.15.0.0/16 is directly connected, Vlan15
L 10.15.40.1/32 is directly connected, Vlan15
