bgp bestpath compare-routerid
bgp by default does not compare the router id of two
different ebgp neighbors
when chosing one to get to x destination . it will
chose the one it learn first from
u can change this by this command and then the lost
router ip router will win
bgp always-compare-med
by default bgp only compeers the med if booth the
routers advertising the network are from the same as
u can change this and it will start comparing the med
value regardless of the as it learned from
bgp deterministic med

bgp bestpath as-path ignore
bgp by default takes the as-path into consideration
when choosing the best route
the less the as the packet has to travel wins , u can
stop the router for taking the as path as a funda
to choose the best route
bgp bestpath med confed
