Dear Experts,

I just want to confirm my understanding regarding the BGP Sync Rule, I read
from Jeff Doyle that the rule said something like this

"prefixes learned IBGP will be put in the IGP routing table or forwarded to
EBGP if only those prefixes available in the IGP Routing table", right ?

I tried to disable the syncronization on the border router but above rule is
not applied... not until the next hope of those prefixes appear in the IGP
routing table....

So my concusion was when sync disabled in the border router the next hope of
the prefixes must be appear in the IGP routing table as well, for those
prefixes to be put in IGP routing table or forwarded to EBGP peer.

Regards,
PU
