opened on Aug 9, 2017

This is in current master (as of yesterday, git sha 9074ba8)

This ONLY happens for ISIS Broadcast Networks if FRR is NOT the DIS.
I set prio to 0 on FRR and 100 on Ixia.
Config is verified against a Cisco and works fine there.

Simple topo. One Interfaces on FRR connected to one (simulated) ISIS router with 200 networks behind.

FRR only gets first 155 (or similar number - not always the same) into the routing table.

Below is the ISIS database. It looks like FRR is ignoring routes which are NOT in the first
LSP.
