Solved: RIP-1 autosummarization

fjcardenas-1 · ‎05-26-2009

I read that RIP-1 supports autosummarization and later in the book it says it does NOT support autosummarization. Which is correct?

Hello Francisco,

RIPv1 is a classful routing protocol that doesn't carry subnet mask info.

It is obliged to perform auto-summary at major network boundary.

RIPv1 doesn't support to disable auto-summary.

RIPv2 supports it and allows for manual summarization out a specific interface RIPv1 cannot do this.

Hope to help
