Quagga in OpenWrt snapshot


I just wanted to test a snapshot version (r26235-0d74b2a1e5) on cudy_wr2100 (ramips/mt7621) but could not find the package "quagga" any more.
Is it discontinued or temporarily unavailable?

I looked at "frr" but it starts 4 daemons takes almost 20 Mb memory for a few ospf routes.
"bird" is running well, but it has no intuitive user interface and so hard to maintain.

Unlike quagga, cisco, etc... birds interface is not used to configure. You use the conf file and then you can use birdc configure to hot reload the config.
Just in case: use bird2.
If you have trouble you can ask again or also post on the friendly bird mailing list.
