[j-nsp] IRB with VRRP configuration issue

[Chris Boyd]

Howdy,

I’ve got an odd issue with an IRB / VRRP configuration that’s driving me a bit crazy.  The physical Ethernet interface is up, but the interface does not show up as part of the “show bridge domain” and the IRB interface shows "Flags: Hardware-Down” which is why I’m guessing the VRRP is also down.

Everything I’ve googled up says “fix the physical interface problem,” but as I pointed out earlier, they are up (devices see each other’s LLDP).  Similar configs are working, so I suspect I’m overlooking something, but sure can’t see it.

    xe-2/1/0 {
        vlan-tagging;
        unit 0 {
            family bridge {
                interface-mode trunk;
                vlan-id-list [ 30 ];
            }
        }
    }

routing-instances {
   our-networks {
        bridge-domains {
            vlan30 {
                domain-type bridge;
                vlan-id 30;
                routing-interface irb.30;
            }

    irb {
        unit 30 {
            family inet {
                address 10.1.1.2/29 {
                    vrrp-group 30 {
                        virtual-address 10.1.1.1;
                        priority 100;
                        fast-interval 200;
                        preempt;
                        accept-data;
                    }
                }
            }
        }
