[BUG] VyOS IS-IS does not use multi-topology for IPv6 #1184
Comments
So now we have a problem with 2 devices (#1171) SR Linux will be adding multi-topology support back shortly, but regardless of that: I still think there is a use case for ipv6 designs that do not use/require multi-topology You can even do dual-stack using a single topology, which has advantages in resource scaling. Could we reconsider making multi-topology mandatory, and add a feature flag to disable it when desired? |
No. You have a problem with one device, and there's a configuration command missing in the IS-IS configuration template of another device. VyOS is using FRR, and we know FRR does multi-.topology. In totally unrelated news, Arista EOS does interoperate with FRR due to FRR creating malformed LSPs, and it doesn't seem like anyone cares enough to merge the PR into frr:master, so whatever. That's why we have https://netlab.tools/caveats/ and caveats in the test reports.
Nice to hear that. I will rerun the tests once the image is available in the public repository.
Absolutely. As we've learned in the past, there's always someone claiming a use case for another nerd knob, and another niche design ;)
... and disadvantages in other aspects, as Peter Paluch told you in a recent LinkedIn discussion.
Nobody asked for this in two years since IS-IS was added to netlab, but you (or anyone else) are more than welcome to add a custom configuration template (or plugin) to your lab topologies if you feel that's needed. |
Looks like VyOS IS-IS CLI does not have a multi-topology setting, but we could tweak the FRR config with
So here are the options:
Which one do you prefer @ssasso? |
I would not manually tweak the FRR configuration, because this will make not aligned the vyos collected config. I will try to open a bug/fr to the VyOS team and/or try to submit them a PR. |
Thank you. Will document it as a caveat. |
It looks like VyOS does not configure FRR to use IS-IS multi-topology for IPv6
