EIGRP? I've never seen IS-IS in any business I've worked with or for in the

Hello
Several people have asserted that IS-IS (for IP) has demonstrated more
scalability than OSPF. What accounts for this? I have heard that it has
to do with IS-IS being able to take advantage of Partial-route Updates when
IP information changes, as opposed to running Dijkstra all the time
Good Question!
I have read that IS-IS can accept more nodes than OSPF. Yet, I find that
Juniper is pushing IS-IS and the US Govt has some networks on IS-IS. Black
in the IP Routing Protocols basically states it is an IP Protocol but is not
used in the internet or much elsewhere for that matter
I still can not leave that question alone. It is a good question. Why is
IS-IS for large networks? The why is the key.

True, both run Dijkstra, but ISIS allow
ackets are required to send 1000s of routes.
Each packet is 532 bytes long.
Don't know how we got here from a question on IS-IS versus OSPF. One design
challenge with OSPF that Chuck alluded to is that sometimes a network
topology doesn't have a good candidate for the area 0 network.
t;obvious high-speed core that could work as Area O.
Actually that's probably not a good way to distinguish IS-IS and OSPF
because IS-IS designs have a similar caveat. IS-IS has its backbone of L2
routers. All inter-area traffic must go through the backbone.

IS-IS is considered more stable because you can manually set the refresh

support over 850 routers in a single area. Try doing that with

Has anyone ever actually seen IS-IS in production? The closest I've ever

I'd also recommend posting to the NANOG list at www.nanog.org. The
discussion of OSPF versus IS-IS is one that is frequently held among network
service providers.
