Technical Tip: Changing Distance and Priority of Default Gateway Learned from PPPoE

[adimailig]

Description	By default, the default route from PPPoE has a distance of 5 and a priority of 1. This article describes how to change the distance and priority of the default gateway learned from PPPoE.
Scope	Fortigate, PPPoE.
Solution	In this example, the distance and priority will be modified as below: Distance: 5 >> 8. Priority: 1 >> 10. Priority preference: lowest value is preferred for the routing table. Distance preference: lowest value is preferred for the routing table. Change Distance : The default gateway route distance can be changed from GUI or CLI. From the GUI:  From the CLI: config system interface     edit "port3"         set distance 8  <- Default value is '5'.     next end Result: FGT_1# get router info routing-table all Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP        O - OSPF, IA - OSPF inter area        N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2        E1 - OSPF external type 1, E2 - OSPF external type 2        i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area        V - BGP VPNv4        * - candidate default Routing table for VRF=0 S*      0.0.0.0/0 [8/0] via 192.168.4.254, ppp1, [1/0]     <- Distance is 8 and Priority is 1. Change Priority: Default gateway route priority can only be changed via CLI. config system interface     edit "port3"         set priority 10       <- Default value is '1'. end Result: FGT_1# get router info routing-table all Codes: K - kernel, C - connected, S - static, R - RIP, B - BGP        O - OSPF, IA - OSPF inter area        N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2        E1 - OSPF external type 1, E2 - OSPF external type 2        i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area        V - BGP VPNv4        * - candidate default Routing table for VRF=0 S*      0.0.0.0/0 [8/0] via 192.168.4.254, ppp1, [10/0]   <- Distance is 8 and Priority is 10.
