ISIS (Broadcast, DIS mode) - missing routes from 2nd etc #4

Closed mwinter-osr closed 7 years ago

mwinter-osr commented 7 years ago

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.

This only seems to happen under specific circumstances, the following database I set up, trying to reproduce the issue, leads to all routes being installed correctly:

Could you provide the output of show isis topology in the failed case?

Here is the config I'm using on the FRR (and on the Cisco where it works):

Cisco Config:

interface GigabitEthernet0/1
 ip address 192.168.100.1 255.255.255.0

FRR Config:

!

 ip address 192.168.100.1/24
 ip router isis test

I'm using ISIS Level-2 (Ixia is net 49.0001), but I've verified that this makes no difference.

This bug was triggered when isisd learned about an LSP fragment from a CSNP first. In that case, a stub entry would be created for the fragment, but not correctly linked in its lsp0, leading to the fragment being ignored by SPF, even when the stub was replaced by the real fragment. https://github.com/FRRouting/frr/pull/961 has been submitted as a fix.

The pull request has been merged into FRR master, in my opinion this issue is fixed. Can you please verify and close the issue if so?
