Hi All,
I know this has been discussed probably many times on this list, but I was
looking for some specifics about what others are doing in the following
situations.
I would like to run an IGP (currently OSPF) to our customers that are
multi-homed in a non-mpls environment. They are multi-homed
Sorry, not OSPFv3. IPv6 thoughts dancing in my head. OSPF-VRF as most of you
probably interpret.

Unless you want your customers to have very substantial control over your
internal network, don't use an SPF IGP like ospf or is-is. You really

Any suggestions what to try?

Scott,
We've had issues in the past with IOS 6500's auto-negotiating uplink ports with
an LTM into ISL Trunk mode. This only occurred when we had the port on the LTM
configured as a tagged interface. It was easily solved by forcing the port on
the 6500 into dot1q encapsulation. I'm not sure thi
Thanks for all the replies so far. Just to clarify, I am in the small
ISP/Hosted services business. I was fortunate to inherit the current setup
of OSPF to the multi-homed customers. As i stated earlier, I would like to

there are certainly many opinions on this subject. However, the most
important factor is - how flexible you wish to be? As you correctly
point out, this is not an issue of what protocol are you going to be
running inside your network. So, "IGP" is not an issue.

On some models I have had to set the BIG-IP's or the 6500 (can't remember

I believe it was auto on the BIG-IP and fixed on the 6500.
Setting both sides the same did not work.
