Where are VPN-IPv4 addresses used in a VPRN? A. In the routing updates exchanged from CE to PE B. In the routing updates exchanged from PE to PE C. In the routing updates exchanged from P to PE D. In customer packets as they traverse the provider core E. In all route tables of the […]

What is the purpose of the Route Distinguisher? A. It defines the VPN membership B. It defines which routes are imported into the vrf C. It defines which routes are exported from the vrf D. It is used to make IPv4 addresses unique E. It is used as the VPN label

VPN-IPv4 addressing is made unique by defining an address structure consisting of: A. A 32 bit IPv4 address followed by a 64 bit Route Target B. A 32 bit IPv4 address followed by a 64 bit Route Distinguisher C. A 64 bit Route Target followed by a 32 bit IPv4 address D. A 64 bit […]

At what point does the Route Target become associated with a route? A. When the route is first received at the P from the PE B. When the route from the CE is populated into the VRF at the PE C. When the route from the PE is populated into the VRF at the CE […]
