Hello, I configure a VTI interface with 'ip link add vti0 type vti local aa.bb.cc.dd remote aa.bb.cc.de' # bird --version BIRD version 1.6.4 # ifconfig vti0 vti0 Link encap:UNSPEC HWaddr C0-A8-03-03-00-00-00-00-00-00-00-00-00-00-00-00 inet6 addr: fe80::5efe:c0a8:303/64 Scope:Link UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1364 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:3 errors:1 dropped:0 overruns:0 carrier:1 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:252 (252.0 B) I configure bird with a static device route through that interface: ... protocol device { scan time 10; # Scan interfaces every 10 seconds } protocol direct testD { interface "*"; } protocol static testS{ route 10.20.0.0/24 via "vti0"; } ... This route is never set unless I configure an IP address on the VTI interface. If I repeat the same steps and use Quagga instead of Bird then route is set. Am I missing something in the configuration? Best regards Alexander Velkov
