How to configure RIP

RIP (Routing Information Protocol) is used for advertising routes to other routers. Thus all the routes in the router's routing table will
be advertised to other nearby routers. For example, the route for the router's Ethernet subnet could be advertised to a Router on
the PPP interface side so that a Router on this network will know how to route to a device on the router's Ethernet subnet. You will have to
add the routes appropriately in the Static Routes section – see Adding Static Routes.
NOTE: it is possible that some routers will ignore RIP.
To enable RIP click on the "Internet Settings" menu followed by "Routing" and then the "RIP" menu item on the right.
Click Enable on the RIP Page
Select RIP version
Click Save RIP

How to configure VRRP

Virtual Router Redundancy Protocol (VRRP) is a non-proprietary redundancy protocol designed to increase the availability of the
default gateway servicing hosts on the same subnet. This increased reliability is achieved by advertising a "virtual router" (an abstract
representation of master and backup routers acting as a group) as a default gateway to the host(s) instead of one physical router.
Two or more physical routers are then configured to stand for the virtual router, with only one doing the actual routing at any given time.
If the current physical router that is routing the data on behalf of the virtual router fails, an arrangement is made for another physical router
to automatically replace it. The physical router that is currently forwarding data on behalf of the virtual router is called the master router.
Master routers have a priority of 255 and backup router(s) can have priority between 1-254.
A virtual router must use 00-00-5E-00-01-XX as its (MAC) address. The last byte of the address (XX) is the Virtual Router Identifier (VRID),
which is different for each virtual router in the network. This address is used by only one physical router at a time, and is the only way that
other physical routers can identify the master router within a virtual router.
To enable VRRP click on the "Internet Settings" menu followed by "Routing" and then the "VRRP" menu item on the right.
Click Enable and to activate VRRP
Enter an ID – this is the VRRP ID which is different for each virtual router on the network
Enter a priority – a higher value is a higher priority
Enter the VRRP IP address – this is the virtual IP address that both virtual routers share
Click Save VRRP
NOTE: Configuring VRRP changes the MAC address of the Ethernet port and therefore if you want to resume with the web configuration you must use the new IP address
(VRRPIP) or on a command prompt type: arp –d <ip address> (i.e arp –d 192.168.1.1) to clear the arp cache.(old MAC address).
