[c-nsp] BGP fast converge

[Mario Velazquez]

Hi, i am having some problems in my metro network, bgp convergence is 
really a problem, i was looking arround for some fast convergence 
features like BGP Fast Peering Session Deactivation and BGP Next-Hop 
Address Tracking. this is what i have so far:
 
a little diagram of what i have:

CE1---SW1----PE1----MPLS----PE2--------CE2
CE3---SW2----PE3                       PE4--------CE4

CE1 and CE3 are in the same site, the same for CE2 and CE4, the CE-PE 
connection is bgp.
All CE are running ospf with more or less than 6000 routes each.
the problem is between CE1/PE1 and CE3/PE3 because when if one port 
fails in SW1/SW2 the bgp session will not be dropped until the dead 
timer expires (180s).

i have this configuration in all CE

outer bgp 222
no synchronization
bgp log-neighbor-changes
network 20.0.0.0
neighbor 1.1.1.1 remote-as 13591
neighbor 1.1.1.1 ebgp-multihop 3
neighbor 1.1.1.1 fall-over
neighbor 3.3.3.3 remote-as 13591
neighbor 3.3.3.3 ebgp-multihop 3
neighbor 3.3.3.3 fall-over
no auto-summary

But nothing seems to change, in the case of a port fail in SW1 or SW2 
bgp stills wait for the peer dead timer.Is there something missing? or 
am i using the wrong feature? or i have a bad config

thanks a lot
