Re: If a cisco router can work as ES in ISO IS-IS topo?

Hello Xu,

refer to the doc

http://www.cisco.com/en/US/docs/ios/isoclns/configuration/guide/configure_iso_clns_ps6350_TSD_Products_Configuration_Guide_Chapter.html#wp1070449

a cisco router can interact with ES but probably can only an IS

So you should build an IS-IS adjacency instead.

You can make the cisco router a L1 only and the other router L2/L1 to be its exit point.

Hope to help

Giuseppe
