[j-nsp] extra ISIS instance showing up...

[Harry Reynolds]

Perhaps like it's the Pseudonode lsp, as sent by the DIS.. 

Its LSPs uses the non-zero Pseudonode ID value.

Subject: [j-nsp] extra ISIS instance showing up...

All,

I have what appeared to be two ISIS instances show up on the "show isis database detail" except the second one ("00-01") doesn't have any TLV info besides the subnets it's advertising for but the weird thing is this second ISIS is never configured. Under the [protocol] there's only one ISIS configure and there's no other routing-instances configured. Anyone have any ideas?
