Time to announce network via BGP

[danny1989]

Hi, I noticed that when I establish a BGP session with my peer, Fortinet takes about 30 seconds to send its routes to the peer. The peer instead sends its routes to Fortinet almost instantly after establishing the session. How can I reduce this time?

Hi,

Try, https://community.fortinet.com/t5/FortiGate/Technical-Tip-Facilitating-the-fastest-BGP-route-failove...

config router bgp
config neighbor/neighbor-group
edit 'ip'/'name'
set advertisement-interval 'integer' <- Minimum interval(sec) between sending updates.(integer= Minimum value: 1 Maximum value: 600, default:30).

I thought about the same timer but isn't it just for "interval" after the first (series of) advertisement was sent out? To me the first one when neighboring is established should go out immediately. Then the interval timer starts counting down and send any updates every 30 sec.

When session is established fortigate sends to remote peer its routes after about 15/20 seconds.. i will try the changes above
