! BGP vs OSPF
!! A pro's and con's investigation

!!! OSPF

||Pro's||Con's||
||Has an entire picture of the network||Multicast Hello's have less than spectacular reliability||
||Can resolve multiple path questions sanely||Has poor administrative controls ||
||Has good support for metrics and metric calculations||No support for FlapDampening ||
||Established on the network||Doesn't match the political structure of the network ||


!!! BGP

||Pro's||Con's||
||TCP based transport||Has less information about specific links within regional groups||
||Better administrative controls|| ||
||Excellent support for FlapDampening|| ||
||Better support for the administrative structure of the network|| ||


Now an initial survey of the above would suggest that BGP is the logical choice for the network.. but the con against it is MASSIVE particularly when you consider that we already have these multipath questions being asked see RGsouthern
