Question

BGP routing in fortigate with two GW

guys i want to receive two default routes from two neighbors on my FG through bgp . and i need both of them to be on routing table ( necessary ) in order to crate and make policy based route working for some subset to use the 2nd default route.

 

i have activated ebgp multipath and when i run the

get router info routing-table bgp -- im able to see the both routing but i need the 1st one to stay as first because if i do clear for bgp routing the order could be replaced for between those two default . so is there anyway to keep first entry always first ( in static route we were able to do it through having same distance with different priority but what to do here )

 

 

 

Ex

FG 3000D # get router info routing-table bgp

Routing table for VRF=0

B* 0.0.0.0/0 [20/0] via 10.10.10.1, To_GW1, 18:05:16

[20/0] via 11.11.11.1 To GW2, 18:05:16

 

I Want the 1st entry( via 10.10.10.1 ) to become always 1st even if i did clear for bgp multi times or if the neighbor went down then returned up

    Are the routes the same or different ? Can you do a "get router info bgp network 0.0.0.0/0" and check the BGP table and not the RIB ?
