in my backbone network i am using ospf and isis routing protocols. In my network i am having the routres that support both ip and isis. i am using both cisco and juniper routers. in one place i want to convert the isis packets to ip packets and i want to transfer the isis packets through ip backbone. guys pls give me some solution.
Thanks for your resonse. Our network is MPLS network . we are using this OSI routers(ISIS) to communicate with some nortal equipments.from nortel equipment then its goes to one ISIS router and then one more ISIS router. After that i want to transfer this packets through IP based routers. In this case redistribution will work. let me know redistribution be configure in OSI router or IP router.
do I understand you correctly, that you need CLNS connectivity across an MPLS backbone? Or is it IP connectivity? Could you please post some more info, why you need ISIS in the network? It would help to find the most suitable solution.
Well in the latter case you should identify one or two routers in your topology, where you have both, OSPF and ISIS and do the redistribution.
If you take two routers for redundancy you might easily get routing loops, so tight filters are required during mutual redistribution.
Thinking about it, there are two more possible options you have:
3) implement Ethernet over MPLS and run ISIS across the ethernet link.
4) if you do not need CLNS, but only IP connectivity (which I can not tell from your posts so far) you could also remove ISIS completely from your network.
The Nortel equipment is attached with some other telecom network. If the Nortel equipment goes down means the NOC want to know. for that only the data network ip or isis. The visibility of the Nortel equipment is via first, using with CLNS and then after the redistribution it is in IP network.NOC can only listen the ip packets.
