Hi All,

  R4 and R5 are directly connecting and running OSPF and BGP, but BGP is not
working as follow:

r5#sho ip bgp sum
BGP router identifier 170.241.127.228, local AS number 100
BGP table version is 1, main routing table version 1

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down
State/PfxRcd
144.1.1.1 4 100 12 12 1 0 0 00:04:24 0
144.2.2.2 4 100 11 12 1 0 0 00:04:15 0
144.4.4.4 4 100 10 10 0 0 0 never Active

r4#sho ip bgp sum
BGP router identifier 170.241.127.228, local AS number 100
BGP table version is 1, main routing table version 1

Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down

144.5.5.5 4 100 10 10 0 0 0 never Idle

And following is the error message:

r4#
