Hey all,
My home router serves a handful of vlans and I have virtualized routers as backups for if / when the primary fails (or I need to shut it down for any reason). I have all of the VLANs in a sync group and each one does the broadcast hello messages and I’m wondering if it’s possible to set one VLAN as the hello network to get all of the multicast traffic off of the other VLANs?.
Here’s my current config:
(assume vrrp_address_number is 1, the root_interface_name is eth1, the vrrp_priority is 100, and the vrrp_vrid is 10, I use ansible to configure the routers)
high-availability {
vrrp {
group VLAN1 {
address 10.0.0.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}
priority {{vrrp_priority}}
transition-script {
backup /config/scripts/vrrp-fail.sh
fault /config/scripts/vrrp-fail.sh
master /config/scripts/vrrp-master.sh
}
vrid {{vrrp_vrid}}
}
group VLAN10 {
address 10.0.10.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.10
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN20 {
address 10.0.20.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.20
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN30 {
address 10.0.30.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.30
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN40 {
address 10.0.40.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.40
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN50 {
address 10.0.50.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.50
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN110 {
address 10.0.110.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.110
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN120 {
address 10.0.120.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.120
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
}
group VLAN200 {
address 10.0.200.{{vrrp_address_number}}/24 {
}
interface {{root_interface_name}}.200
priority {{vrrp_priority}}
vrid {{vrrp_vrid}}
