You are logged into a Junos device and issue the command show route protocol bgp. You see that the device has received the route 10 0.4/24 from two different
IBGP peers. Local preference, MED, origin, and AS-path values are equal.
Which criterion is used to determine which path will be preferred?

A. cluster length

B. router ID (RID)

C. peer ID

D. IGP cost








 

Suggested Answer: B



When a Junos device receives two similar route advertisements from different BGP peers, it will select the route will the lowest MED value. BGP route selection proceeds in this manner:
✑ Prefer the highest local-preference value
✑ Prefer the shortest AS-path length
✑ Prefer the lowest origin value
✑ Prefer the lowest MED value
✑ Prefer routes learned from an EBGP peer over an IBGP peer
✑ Prefer best exit from AS
✑ For EBGP-receive routes, prefer the current active route:
✑ otherwise, prefer routes from the peer with the lowest RID
✑ Prefer paths with the shortest cluster length
✑ Prefer routes from the peer with the lowest peer ID
