ISIS extended IS/IP reachability

[moods]

Hi,

doing some IOT between ALU and some other vendor and ISIS database is not populated on the other node (adjacency is up)

Does ALU by default send both "normal" and extended IS/IP reachability? I do not have traffic engineering enabled.

Code: Select all

Thanks for feedback

Which TLVs are you talking about?

Should be no issue with interop.

I think you've sort of answered your own question. I believe you need traffic-engineering (and wide metrics) enabled for the extended IS reachability TLV.
