Anybody understand what a BGP state of NoNeg is?

I have 2 Cisco's (a 10008 and a 7513) and a Juniper M20. BGP all meshed.
Both the sessions to the Juniper have this NoNeg state.

7513#sh ip bgp sum
BGP router identifier 192.233.1.10, local AS number 6745
Neighbor        V    AS MsgRcvd MsgSent   TblVer  InQ OutQ Up/Down
State/PfxRcd
192.233.1.4     4  6745    1502    1516        3    0    0 01:26:10        0
192.233.1.6     4  6745   11517   11543        0    0    0 00:09:35 (NoNeg)

With diff command on the Cisco's :-

7513#sh ip bgp neighbors 192.233.1.6
BGP neighbor is 192.233.1.6,  remote AS 6745, internal link
 Description: Juniper
 Member of peer-group gblx-VPNv4-mesh for session parameters
  BGP version 4, remote router ID 192.233.1.6
  BGP state = Established, up for 00:49:19  <<<<<<< ??

10008>sh ip bgp neig

Any thoughts/ideas?
