Default Route Addition Fails

johnoatwork

Hi All,

I've run up the latest Home Lab version of tnsr and have started configuring. I initially set the default route using the instructions at https://docs.netgate.com/tnsr/en/latest/routing/default.html and was able to ping external hosts. However, I lost the config when I restarted as I hadn't copied it to the startup config.

Now, when I follow the same steps I get this message:

"Commit failed.: application operation-failed add:vpp/route/0.0.0.0/0, Unknown nlmgmt error, Route add failed
CLI command error"

tnsr looks like it will solve a problem for me and I'm pretty keen to get proof of concept working.

Can anyone out there help?

There appear to be two instances of the routing table for IPv4 and IPv6. Is this normal?

tnsr(config)# show route

Route Table ipv4-VRF:0  AF: ipv4  ID: 0
-----------------------------------------

Route Table ipv4-VRF:0  AF: ipv6  ID: 0
-----------------------------------------

Route Table ipv6-VRF:0  AF: ipv4  ID: 0
-----------------------------------------

Route Table ipv6-VRF:0  AF: ipv6  ID: 0
-----------------------------------------

Solved. You need to include the device when specifying the route e.g.

next-hop 0 via xxx.xxx.xxx.xxx WANPORT0

The steps set out at https://docs.netgate.com/tnsr/en/latest/routing/default.html don't specify this. I expect the reason it worked initially is that there was only one interface when I first configured the route.

You don't need to specify the interface on a route if the next hop is in a directly attached subnet on an interface. It's possible that for some reason that interface was temporarily unavailable (not enabled, for example) so it couldn't resolve the route.

There was also a possibly related bug somewhere along those lines which is fixed in the 21.11 release that is coming very soon.

Thanks jimp. Maybe just a newbie issue. Anyway, I've got an initial build up now. Throughput is about twice as fast as testing I've done with FreeBSD packet filters but still tops out at about 3-4Gbps. I'm hoping I can improve this with tuning.

Looking forward to the next release. Debian distro's are my preferred Linux flavour
