FRR 10.4.0 is out

Here are the release notes: https://frrouting.org/release/10.4.0/

Thank you. Ran the integration tests a few days ago, found two bugs, @ton31337 fixed them, and the fix was merged earlier today (FRRouting/frr#19277). Waiting for .1 release.

Also found those. I do not know why the original author abandoned them. Without them (or at least the subset which leaks L1 routes into L2 ) , any hierarchical ISIS network is broken, as you already know.

I should try contact those people and get things moving again. Maybe breaking that mammoth patch in several pieces , and start with the most important items will get it merged incrementally, and finally yield a functional ISIS in FRR.

When you can run hundreds (some people claim over 1000) routers in a single area, the motivation to implement proper inter-level route leaking drops to negligible levels ;)

[DanPartelly]

Part of that patch is non-trivial, so there should have been some amount of motivation, at least initially. But yeah, I get your point =)

Update: 10.4.1 is out and is failing the EBGP unnumbered incoming BGP policy test due to slow propagation of EBGP prefix over IBGP. Already sent an email to @ton31337 ;)

Update: The https://github.com/ipspace/netlab/blob/dev/tests/integration/bgp.policy/22-locpref-unnumbered.yml test was failing because I checked for IPv4 IBGP session, but not for IPv6 one. That has been fixed now (eaba177) and FRR 10.4.1 passed all tests (c3ec5a0).

I updated the FRR release in device settings (e79219c)

Thanks for the update.
