Hi,

I have a FR P-M interface on R3 connecting to R4 & R5, R3 establishes BGP
connection to R4 but R3 -> R5 is getting hold time expired message, no luck
with google,

R3#sh run | in nei
 neighbor 154.1.0.4 remote-as 400
 neighbor 154.1.0.5 remote-as 400

R3#sh ip bgp s | be Neighbor
Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down
