Configuring VRRP

Configuring VRRP   To configure VRRP you must configure two or more FortiGate interfaces or routers with the same virtual router ID and IP address. Then these FortiGate units or routers can automatically join the same VRRP group. You must also assign priorities to each of the FortiGate units or routers in the VRRP group. […]

IPv6 in dynamic routing

IPv6 in dynamic routing Unless otherwise stated, routing protocols apply to IPv4 addressing. This is the standard address format used. However, IPv6 is becoming more popular and new versions of the dynamic routing protocols have been introduced. Dynamic routing supports IPv6 on your FortiGate unit. The new versions of these protocols and the corresponding RFCs are: […]
