Ip route to uci

Installing and Using OpenWrt Network and Wireless Configuration
1

Hi,

So im trying to get avahi to work on wireguard this works when i use:

ip link set multicast on dev wifivpn (can also be enabled on the dsa device).
ip -4 route add 224.0.0.0/4 dev wifivpn

But what would be the uci version of ip -4 route add 224.0.0.0/4 dev wifivpn?

I have tried to make static route but when i restart the router the ip route doesn't show a route with 224.0.0.0/4

My network config:

config route
        option interface 'wifivpn'
        option target '224.0.0.0/4'
        option onlink '1'

but the output from when i manually add the route is:

224.0.0.0/4 dev wifivpn scope link

Why does the static route from luci/uci does not get added to ip route?

Set route type to multicast.
Show

ip -4 ro sh

avahi uses significantly smaller IP range than /4

This is the result of the ip route command:

root@MT6000:~# ip -4 ro sh

192.168.99.0/24 dev br-lan.6 proto kernel scope link src 192.168.99.1
<Snip> dev pppoe-wan proto kernel scope link src <snip>

Though i dont see the route added.

new result of config:

config route
        option interface 'wifivpn'
        option target '224.0.0.0/4'
        option onlink '1'
        option type 'multicast'
4

Maybe remove 'onlink' option?

I have been trying to play a little with this.

It seems it works when i specify a table:

config route
        option interface 'wifivpn'
        option target '224.0.0.0/4'
        option type 'multicast'
        option table 'main'

now ip -4 ro sh also shows:

multicast 224.0.0.0/4 dev wifivpn proto static scope link

Thanks :+1:
