Question 18

In inter-AS model C VPRN, which of the following about the command "advertise-label ipv4" is TRUE?

This command is required on all PE routers to distribute labeled IPv4 routes directly to PEs in remote AS.

This command is required on the ASBRs to exchange labeled IPv4 routes between the ASs.

This command is required on the route reflectors to exchange customer routes between ASs as labeled IPv4 routes.

This command is required on all PE routers to distribute labeled IPv4 routes to connected CEs.

Question 19

Which of the following about inter-AS model B VPRN is TRUE?

Model B requires the configuration of back-to-back VRFs between the ASBRs in different autonomous systems.

Model B is highly scalable because the VPN-IPv4 routes are neither maintained, nor distributed by, the ASBRs.

There is a dependency between the route target used in different autonomous systems.

Model B supports the exchange of labeled IPv4 routes between ASBRs.

Question 20

Which of the following about inter-AS model B VPRN is FALSE?

Model B does not require the configuration of VPRN instances on ASBRs.

The ASBRs peer with each other to transport VPN-IPv4 routes between autonomous systems.

PE routers distribute VPN-IPv4 routes to their local ASBR.

One single ASBR is required in each AS to hold the routes for all VPRNs.
