Hi all,
IS-IS is defined to work with CLNP not for IP originally. Until today a lot
of SONET and telecommunication equipment vendors still use IS-IS to route
CLNP packets through the SONET Data communication channel(DCC) to carry
management information and there is a great pressure to change this to OSPF
and IP. I also know that UUNET runs IS-IS on their network. I never heard
any other networks run IS-IS. Seems I am wrong. My questions are.
1. You guys are talking about using IS-IS in a IP networks not in CLNP
networks. The IS-IS has been modified according to RFC 1195 (Use of OSI
IS-IS for Routing in TCP/IP and Dual Environments) or some other standard.
Is this correct?
2. Besides UUNET, which ISPs run IS-IS protocol? Can you name a few? or
what percentage of networks run IS-IS instead of OSPF?
Thanks
David

Subject: MPLS and IS-IS
Hi all,
I have been hearing IS-IS is a better protocol to be used than OSPF in a
MPLS
network for TE application. Is that a fair statement? What are the technical
reasons?
Appreciate if someone can shed some light on this subject.
Thanks,
Hansen
