Why laugh at me applying in out.
Weight – apply inbound to influence outbound traffic.
local-pref – apply inbound to influence outbound traffic.
as-path – apply outbound to influence inbound traffic.
med – apply outbound to influence inbound traffic.

“We Love Oranges AS Oranges Mean Pure Refreshment”
W Weight (Highest)
L Local_Pref (Highest)
O Originate (local originate)
AS As_Path (shortest)
O Origin Code (IGP < EGP < Incomplete)
M MED (lowest)
P Paths (External Paths preferred Over Internal)
R Router ID (lowest)

We – weight
Love – local preference
Algorithms – as-path
On – Origin
My – MED
Router – router-id

Discard all Worries before Leaving Rome As the Original Mis-information
Sound’s like a Neighbor’s Idea.
Discard = DISCARD unreachable next hop.
Worries= highest WEIGHT
Leaving=highest LOCALpreference
Rome=Originated on this ROUTER
As=shortest AS_PATH
Original=ORIGIN code
Mis-information=lowest MED
Sound=SOURCE (external or internal)
Neighbor’s=Closet IGP NEIGHBOR
Idea=lowest router ID
