I have one Radius Server which on its gateway is 192.168.1.1 but is connected to two routers, my question is how do i set gateway address on each router and if one router fails?
How many LANs do you have?
Gateway functions upwards, not downwards.
Since according to your drawing your server is connected to both routers, then it already must use two gateways.
Just specify the IP of the router interface/bridge for each respective interface on the server.
Normally such two routers means at least 2 LANs. Ie. a multihomed server.
Many thanks for replies - in VRRP examples ( https://wiki.mikrotik.com/wiki/Manual:VRRP-examples ) load sharing looks promising but as the radius server has just one gateway ( 192.168.1.1) , Could I set in R1 and R2 the same gateway IP?
Configuration
R1 configuration:
/ip address add address=192.168.1.100/24 interface=ether1
/interface vrrp add interface=ether1 vrid=49 priority=254
/interface vrrp add interface=ether1 vrid=77
/ip address add address=192.168.1.1/32 interface=vrrp1
/ip address add address=192.168.1.1/32 interface=vrrp2
R2 configuration:
/ip address add address=192.168.1.200/24 interface=ether1
/interface vrrp add interface=ether1 vrid=49
/interface vrrp add interface=ether1 vrid=77 priority=254
/ip address add address=192.168.1.1/32 interface=vrrp1
/ip address add address=192.168.1.1/32 interface=vrrp2
Just to add another question will VRRP work on VLAN interfaces
R1 configuration:
/ip address add address=192.168.1.100/24 interface=Vlan100-Ether1
/interface vrrp add interface=Vlan100-Ether1 vrid=49 priority=254
/interface vrrp add interface=Vlan100-Ether1 vrid=77
/ip address add address=192.168.1.1/32 interface=vrrp1
/ip address add address=192.168.1.1/32 interface=vrrp2
R2 configuration:
/ip address add address=192.168.1.200/24 interface=Vlan100-Ether1
/interface vrrp add interface=Vlan100-Ether1 vrid=49
/interface vrrp add interface=Vlan100-Ether1 vrid=77 priority=254
/ip address add address=192.168.1.1/32 interface=vrrp1
/ip address add address=192.168.1.1/32 interface=vrrp2
Just to add another question will VRRP work on VLAN interfaces
Yes.
But I have seen exemples in this forum with VRRP on VLAN, https://forum.mikrotik.com/viewtopic.php?p=1001060 but also VLAN’s on VRRP.
The later probably to make all VLAN fail over at the same time ??? Lost the link to that one.
