Thanks to all for the responses to my VPN connections.
I have pretty much verified it will work in an
"active/failover" setting...
Now, I have an issue where I need to convince my
customer that it's better to subinterface a fast
ethernet port into two separate VLANs rather than add
secondary IP a
Secondarys will really hurt you in a DHCP environment. The workstations on
the secondary subnet will get their DHCP request forwarded with a source
segment of the initial IP address on the interface. This was good ammo for
me when I was in the same boat.

Actually using secondaries and DHCP should be a non issue with
any reasonable DHCP server platform. As you mention, in many
versions of IOS the interface's primary IP address is used
as the DHCP giaddr. If an interface has multiple secondaries,
one just needs to configure the DHCP server to be a

touch the reasonable DHCP server platform statement. That
sounds like an MS bashing in the waiting :)

Argh. Tab and return doesn't work well in when posting through
the web page
Let me revise the last part of my message:
If the interface (or sub-interface) looks like:
int ethernet 4/0.42
ip address 10.0.1.1 255.255.255.0
ip address 10.0.2.1 255.255.255.0 sec
ip address 10.0.3.1 25
Thanks for all the info p b. It's very helpful.
Regarding the first situation, where the DHCP server is on another segment
and we're using a helper address to get the requests over to the server:
We have established that if you use secondaries, the router puts its primary
address into the giaddr

Ah, ok. I think I see some of the confusion. Recall that one
can configure sub-interfaces with secondaries:
int ethernet 4/0.10
ip address 1.2.3.1 255.255.255.0
ip address 2.3.4.1 255.255.255.0 secondary
ip helper-address 99.88.77.66
int ethernet 4/0.20
ip address 3.4.5.1 255.255.255.0
