おいおい、ちゃんとRouteあるぞ。

r3.inet.0: 16 destinations, 16 routes (16 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both

   : <snip>
192.168.100.1/32   *[OSPF/10] 20:33:39, metric 2
                    >  to 192.168.4.2 via et-0/0/30.0

Routing-instanceの中に終端する時には、以下のOptionが必要なそうだ。

root@TSUTSUJIGAOKA# show interfaces gr-0/0/0 
unit 0 {
    tunnel {
        source 192.168.200.1;
        destination 192.168.100.1;
        routing-instance {
            destination r3;
        }
    }
    family inet {
        address 192.168.10.2/30;
    }
}

 

Routing-instance内にInterface書いてるのに変なの。

    instance-type virtual-router;
    routing-options {
        rib r3.inet.0 {

    protocols {

                interface gr-0/0/0.0 {

    }
    interface gr-0/0/0.0;
    interface et-0/0/30.0;
    interface et-0/0/31.0;
    interface lo0.2;
}

ちゃんとUpした。
