Re: BGP timers

What are the timers for the underlying IGP?

You should leave some room for IGP convergence, then adjust the timers on BGP.

I've seen values in the 5/15 range but that's quite aggressive. Usually, 10/30 is the norm after modifying OSPF to 5/15 for instance.

Re: BGP timers

Hi Edison,

Thank you for the quick reply. Router is peering with ISP and sitting out side of ASA. But looks like ISP using OSPF as IGP with no changes to OSPF timers (my end router has plain OSPF config). So 10/30 is norm, then I will go with that.

Thanks again

If you go with 10/30, make sure to change the OSPF timers to 5/15 on every OSPF device on that segment.
