Since my FAQ on the JNCIP-M continues to be one of the most popular posts I have written here on my blog, I guess it makes sense to compliment that with a similar FAQ for the JNCIE-M lab exam. For consistency, I will try and answer all the same questions I did for the JNCIP [...]

MPLS/BGP Provider-Provisioned VPNs, such as those proposed in RFC 4364 (formerly RFC 2547) or draft-kompella variants, suffer from some scalability issues due to the fact that all PE routers are required to have a full iBGP mesh in order to exchange VPN-IPv4 NLRI and associated VPN label information. In a modern network consisting of a large number of [...]

JUNOS now support MPLS-in-GRE & MPLS-in-IP. You guys can now encapsulate the MPLS label stack for a packet with an IP header, making it possible to tunnel MPLS over networks that do not have MPLS enabled on their core routers. The JUNOS software su…
