IS-IS ?

Hi,

I have just started to learn about IS-IS.

Utterly confusing for now.

I'd ask the network engineers outthere for their opinions in relation with that protocol -

where is it typically encountered, what is the future of it, what is the recommended lab setup for studying,

how much coverage on the BCSI exam - and anything else I didn't ask,

that I should know about ISIS.

Thanks in advance !

Re: IS-IS ?

We have setup ISIS routers using CLNS routing here in the Philippines. Most applications are for NMS. You can configure a router ring with each serial interface having different area addresses and NSAP.

Re: IS-IS ?

IS-IS is a very scalable, link state routing protocol which can be used to route CLNS, IP or both protocols.

There are some similarities between ISIS and OSPF and there are some major differences as well.

You will typically find ISIS running in major ISP and Enterprise networks.

The BSCI exam covers ISIS, but some parts are confusing.

I would recommend you read the ISIS chapter from Jeff Doyle's "Routing TCP/IP vol. I". It's much more clear than in BSCI.

Cheers
