Juniper BGP, Configuration Manual

■
path attribute entries—Number of distinct path attributes stored in BGP's
internal path attributes table. If BGP receives two routes for different prefixes
but with identical path attributes, BGP will create only one entry in its internal
path attribute table and share it between the two routes to conserve memory.
■
Prefix—Prefix for the routing table entry
■
Peer—IP address of BGP peer
■
Next-hop—IP address of the next hop
■
MED—Multiexit discriminator
■
CalPrf—Calculated preference
■
Weight—Assigned path weight
■
Origin—Origin of the route
■
