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

144.4.4.4 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

144.5.5.5 4 100 10 10 0 0 0 never Idle
And following is the error message:
r4#
