Ascend GRF

PSI used to feed our site with a Cisco 7xxx and changed to a GRF400. The

noticed a substantial difference in the speed with which the advertisements
roll in. Either upstream box pumped out the BGP advertisements when the
line first comes up at about 60% of the T1. Neither box pushes harder than

There were some problems (non-BGP) when PSI first tried to activate the
GRF, but those appear to have been resolved.
