hi...

i have cisco ASA configure with OSPF routing to corporate DS switch.
behind ASA is cisco 3650 vlan layer 3 routing configured.

when i do show route from other office, i only can see the subnet that is IP interface configured at ASA able published. other subnet that at 3650 swtich doesn't appear.

how can i force those subnet to publish to MPLS as well.
i have given a single subnet and custom it to /27

thanks

Nope. is configured at ASA.
3650 only do static route to ASA, 0/0 --> ASA
and ASA also have static route through back VLAN traffic to core switch - 3650

I assume on your ASA you have static routes towards the 3560, for the networks behind it.

In that case, on the ASA, you need to "redistribute static subnets" under OSPF, for it to advertise these into OSPF.
