Hi All,
From different publications, i have come across different ways of configuring CSCs "hierachical". At times it is the P routers that reflect routes to the ASBRs and sometimes the ASBRs peers with each other, just like option3 of Inter-AS. May i therefore ask anyone to please explain why the discrepancies in these configs and in anticipation for the future SP lab, which is the most viable option?.
Thanking you all in Advance,
