BGP contains two paths to a destination. Assuming both routes were originated locally and
have an equal weight. what will be the next determining factor in choosing the best path?
A.
lowest MED
B.
highest local preference
C.
lowest neighbor IP address
D.
lowest origin code
E.
shortest AS-path
Explanation:
Memorizing the BGP decision process steps is very useful and you should remember them.
The table below lists the complete path selection process:
1. Weight (Bigger is better)
2. Local preference (Bigger is better)
3. Self originated (Locally injected is better thaniBGP/eBGP learned)
4. AS-Path (Smaller is better)
5. Origin (Prefer ORIGIN code I over E, and E over ?)
6. MED (Smaller is better)
7. External (Prefer eBGP over iBGP)
8. IGP cost (Smaller is better)
9. EBGP Peering (Older is better)
10. RID (Lower is better)
