Are there any tricks to auto-summarize the contents of a RIB where the tributary routes are not originated locally?
Example:
Input routes:
prefix: 1.0.0.0/16, next-hop: 5.5.5.5
prefix: 1.0.1.0/16, next-hop: 5.5.5.5
prefix: 1.0.2.0/16, next-hop: 4.4.4.4
prefix: 1.0.3.0/16, next-hop: 5.5.5.5
Consolidated, Installed routes:
prefix: 1.0.0.0/14, next-hop: 5.5.5.5
prefix: 1.0.2.0/16, next-hop: 4.4.4.4
Basically a way to consolidate total number of prefixes entering the FIB.
If such a thing existed we could feed non-Juniper, TCAM-based routers a smaller table but still maintain the advantages of best path, hot potato routing.
