Dear All,
Thanks once again for the advice. Just a few questions.
As far as unnumbered, my .02 is that it's not worth the hassle. Using
unnumbered to customers means you need to have enough address space in
your loopback so that you don't have two customers with the same IP
address connected to the same box. And IP unnumbered in the core your
network is a Bad Idea; *very* difficult to troubleshoot problems if
traceroute doesn't tell you anything about which physical link you
cross.
Question: If I am looking at using IP Unnumbered for NON-MPLS circuits,
Could'nt I do good with one loopback address per aggregation router?
Question: Is it preffered to use IBGP on aggregation routers, & announce
customer prefixes into the network using IBGP, instead of treating them as
external / stub links ie in the case of OSPF reducing overhead in the IGP,
& also reducing the floating of LSA's.
Kindly advice me.
With warm regards,
Vinod.
