Hi there :) I'm just wondering if it is possible without hard/soft reset to update routes on BGP.
I guess hard/soft reset is only needed when you wanna update route or apply the new policy. If I don't use hard/soft reset, what happens ?
Is it still updated ? I guess it's only updated by new incoming updates or outcoming updates that expires update periods, am i right ?
I have no idea :(
'clear ip route' should do it.
You don't need to reset if you're adding or deleting routes. But changing route maps that do things like set communities or prepends usually requires a reset to take effect.
clear ip bgp neighbor (either neighbor address or * for all) also will clear all BGP learned routes and relearn routes from the BGP peers
If my memory server me correctly you can do a soft reset inbound or outbound to your bgp peers as follows:
clear ip bgp X.X.X.X soft in / out - where X.X.X.X is the neighbor.
I don't have a router to hand to test but I think that's right.

Darren
