Issue with intervlan routing

I have a wired subnet (VLAN 1) that has SVI 192.168.1.1  The att modem is 192.168.1.254

I have a wireless subnet (VLAN 2) that has SVI 192.168.86.254.  The wireless router is 192.168.86.1

From the Nexus 3K I can reach all devices

I am unable to ping between devices between VLAN 1 and VLAN 2 and vice versa

ip route 192.168.1.0/24 Vlan1 192.168.1.254
ip route 192.168.86.0/24 Vlan2 192.168.86.1
vlan 1
vlan 2
name wireless
vlan 3
name wired

spanning-tree vlan 1 priority 24576
service dhcp
ip dhcp relay
ip dhcp relay information option
ipv6 dhcp relay
vrf context management
ip route 0.0.0.0/0 192.168.1.1

Hey bct0109,

Have you enabled "ip routing" on the Nexus? Let me know if this is able to help!

Which context should I run it from?  Global context requires more syntax.  Do my default routes look correct?

 

MBNET-3048(config)# ip routing
event-history internal multicast
MBNET-3048(config)# ip routing ?
event-history Configure routing event log
internal Commands for internal use
multicast Configure multicast

MBNET-3048(config)# ip routing

 

 

Thanks

Running it from global without any syntax should be sufficient. 

Additionally, is there a reason you’ve specified two DHCP relays on VLAN1? Is all ports on your switch routed ports, or is traffic being forwarded through any switch ports?

On the DHCP server have you set the default router address (DHCP option 3) within the DHCP pools?
