5.2 -- MSDP originator ID required?
I understand why the solution has "ip msdp originator-id loopback x" -- to avoid possible duplicate router IDs in MSDP messages due to the loopback interface being anycasted -- but is this required for this answer to be correct?
My understanding is if there's only 2 MSDP members, a relaxed set of rules is used and the originator ID is ignored for loop prevention -- even if it a duplicate.
Furthermore, MSDP tested out ok (but I did not force it to be a duplicate ID -- the particular non-msdp loopback was numerically higher anyways so it wouldn't have used a duplicate RID).
For these two reasons (although I can't say which), I think this should still be correct without originator ID specified? Or is it wrong?
