[alcatel-nsp] bgp min-route-advertisement

[Alexander Saveliev]

Hello,

This is true, especially for address-family with full view.
But also true is that in bgp/mpls vpns often there are no many peering 
points and no full view of internet routes. 30sec restriction 
significantly reduces convergence time in this networks, especially in 
redundant topologies.
So it is common practice, from "another vendor" for example, to set 
default time for eBGP sessions in GRT equal to 30 secs, but to set it 
equal to zero secs for iBGP and for PE-CE sessions in VPNs.

Ok. My main question is- may be somebody know something important about 
ALU routers that can have a serious negative impact when setting 
advertisement equal to 1 sec?

Thanks,
Alexander
