Question 4

Which statement about the Cisco MPLS TE forwarding adjacency feature is true?

Accepted Answer

Question 6

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

Accepted Answer

Link-state routing protocols maintain a complete view of the network topology, which allows MPLS TE tunnels to evaluate the entire topology and determine the most efficient path for traffic.

Question 7

After you analyze your network environment, you decide to implement a full separation model for Internet access and MPLS L3VPN services. For which reason do you make this decision?

Accepted Answer

Separating Internet access and MPLS L3VPN services allows EGP (External Gateway Protocol) and IGP (Internal Gateway Protocol) to operate independently, reducing complexity and potential conflicts between the two.

Question 17

While implementing TTL security, you issue the PE(config-router-af)#neighbor 2.2.2.2 ttl-security hops 2 command. After you issue this command, which BGP packets does the PE accept?

Accepted Answer

The command sets a TTL security check for BGP packets, meaning the PE will only accept packets from 2.2.2.2 if they have a TTL of 253 or more, ensuring they are from a directly connected neighbor.
