Dear All,

I'm working on IE-11 lab. I'm facing a problem with isis configuration. I
tried to configure two areaes on the same isis process and I just keeping
receive this error message

the network layout is

%CLNS-3-BADPACKET: ISIS: LAN L1 hello, Duplicate system ID detected from
0030.1950.0f10 (FastEthernet1/0)

The configuration is
