James, one question for you, are VLAN 27 and VLAN 30 on a trunk port? If they are on a trunk port and the remote is down, the default will not withdraw from the routing table without some type of IPSLA.
If VLAN 27 and VLAN 30 is the not on a trunk and just dedicated to port for the remote switch, why don't you make it a routed port (no switchport). Or better yet, use dynamic routing protocol.
I just tested in my lab. It works great. Here is an email I just sent out with the results:
In normal production you can see that there are routes to all the directly connected networks and specifically there is a "gateway of last resort" set to the primary route as shown below (note this is a lab environment so not all production VLANs are represented):
Gateway of last resort is 192.168.70.1 to network 0.0.0.0
172.30.0.0/24 is subnetted, 1 subnets C 172.30.192.0 is directly connected, Vlan2 192.168.70.0/30 is subnetted, 2 subnets C 192.168.70.4 is directly connected, Vlan30 C 192.168.70.0 is directly connected, Vlan27 S* 0.0.0.0/0 [1/0] via 192.168.70.1
Now, when I unplug the cable in port G1/0/47 which is in access vlan 27, the output of the show ip route command is as follows:
Gateway of last resort is 192.168.70.5 to network 0.0.0.0
172.30.0.0/24 is subnetted, 1 subnets C 172.30.192.0 is directly connected, Vlan2 192.168.70.0/30 is subnetted, 1 subnets C 192.168.70.4 is directly connected, Vlan30 S* 0.0.0.0/0 [250/0] via 192.168.70.5
Here you can see that the default gateway has automatically failed over to 192.168.70.5 and that VLAN27 has been completely removed from the routing table. The failover was immediate. As soon as the port goes down the routing table is updated.
The ports are not trunked...they are just access ports. So in the event of the link going down on the port associated with VLAN27, the failover will happen.
