Hello, I'm new to vPC technology. I read many informations on the loop avoidance mechanism which rely on "logics implemented directly in hardware on vPC peer-link ports". vPC loop avoidance rule states that traffic coming from vPC member port, then ...

Hello, Is-it possible to insert a static and an eBGP path in the RIB for the same prefix on Cisco IOS XE ? Even modifying static route metric to be equal to eBGP administrative distance (20), static path prevail over eBGP path. Help would be greatl...

Hello, Do you have any idea of the proportion of ISPs running BGP free core network (i.e. label-switching Internet traffic) ? Which one for example ? Best regards, Thomas

Does someone verifed Luc De Ghein's assertion below ? If a prefix is reachable via a mix of labeled and unlabeled (IP) paths, Cisco IOS does not consider the unlabeled paths for load-balancing labeled packets. (page 50, MPLS Fundamentals, Cisco Pre...

I started wondering if it was possible to get a functional OSPF neighborship between two routers without a PVC connecting them in a one-subnet-three-routers-over-frame-relay topolgy (first attachment, GNS3 topology and configurations files using c37...

Thank you Richard

Thank you Philip for your answer, I know that some big ISPs provide Internet access and MPLS VPN services to their customers. I wonder if they only have one core network that support both Internet and VPN traffic (i.e. all traffic is label-switched) ...

Hello Masoud, I made a new scenario : https://trupel.com/networking/Lists/Billets/Post.aspx?ID=6 Same observation as in the previous scenario : load-balancing don't occur. Thomas

Hello Giuseppe, I made another scenario to observe load-balancing between labeled and unlabeled path at the core level on a plain IPv4-over-MPLS network : https://trupel.com/networking/Lists/Billets/Post.aspx?ID=6 As you said, it seems Luc's assertio...

Hello Masoud, I think Luc's assertion is platform dependent. But as you suggested, observing load-sharing between core and edge routers is not the best point of view to prove Luc's assertion. To confirm or invalidate Luc's assertion (at least for CSR...
